MJE13005 NPN Transistor Datasheet, Pinout, Features & Applications

Hi Guys! I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to MJE13005. The MJE13005 is a high speed and high voltage power transistor that belongs to the NPN transistor family. This device can support load up to 4A and the emitter-base voltage is 9V which is the voltage required to bias the device and start the transistor action. I suggest you read this post all the way through as I’ll detail the complete Introduction to MJE13005 covering datasheet, pinout, features, and applications. Let’s get started.

Introduction to MJE13005

• The MJE13005 is an NPN transistor which is a high speed and high power device used for amplification and switching purposes.
• This component is made of three-layers where one is p-doped layers and the other two are n-doped layers. The p-doped layer stands between these two n-doped layers.
• The MJE13005 is a semiconductor device made of silicon material. It contains three terminals known as emitter, base, and collector and is termed as a current-controlled device as opposed to MOSFETs which are voltage-controlled devices and contain terminals source, drain, and gate.

• All these terminals carry different doping concentrations. The doping concentration of the collector pin is light and the doping concentration of the emitter pin is high compared to the other two terminals. The base pin is 10-times more doped than the collector pin. Moreover, the emitter side carries the entire current of the device since the emitter current is the sum of both collector current and base current.
• The bipolar junction transistors are mainly categorized into two types i.e. NPN transistors and PNP transistors.
• Both electrons and holes play a vital role in conductivity in both these transistors. But in the case of NPN transistors holes are the majority carriers and in the case of PNP transistors holes are majority carriers.
• The NPN transistors are preferred over PNP transistors for a range of applications because the mobility of electrons is better than the mobility of holes.
• NPN devices are sometimes known as “sinking devices” since they sink ground to the output. PNP devices are sometimes named “sourcing devices” since they source positive power to the output.
• The DC current gain of this device ranges from 8 to 40 which is the amount of current this device can amplify.

Before you embed this device into your electrical project, it’s wise to scan through the datasheet of this component that features the main characteristics of the device. Click the link below to download the datasheet of MJE13005.

MJE13005 Pinout

The following figure shows the pinout diagram of MJE13005. This device contains three terminals named:

1. Base
2. Collector
3. Emitter

The small current at the base side is used to produce a large current across two terminals. This device carries two junctions i.e. base-collector junction which is reverse biased and base-emitter junction which is forward biased.

MJE13005 Working Principle

• The working of this device starts from the base pin. When voltage is applied at the base pin, it results in biasing the device, and current starts flowing from collector to emitter terminal.

• Know that these bipolar junction transistors are not symmetrical devices. This means if we exchange both emitter and collector terminal, it prevents both these terminals to work in forward active mode and as a result, both these terminals will start working in reverse active mode. Doing this will affect the values of common-emitter current gain and common-base current gain.

• This lack of symmetry comes from the different doing concentrations of all three terminals.
• The Common-emitter current gain of this device ranges from 8-40 in this device, which is denoted by beta and the common-base current gain is denoted by alpha and is always less than one.

MJE13005 Equivalent

The following are the alternative to MJE13005:

• KSE13007
• MJE13007
• 2SC3795

It’s better the check out the pinout of alternatives before applying them to your electrical project as the pinout of the alternatives might differ from the pinout of MJE13005.

• The IRF2807 is an N-channel MOSFET that comes with a power dissipation of around 200W.
• This device is mainly used for fast switching applications and low thermal resistance and low package cost makes this advice an ideal pick for a range of industrial applications.
• The IRF2807 contains three terminals called the gate, drain, and source. At times, this is considered as a four-terminal device when the body is taken as the fourth terminal of the device.

• The electrons enter the channel through the source terminal while they leave the channel through the drain terminal. The gate terminal plays an important role in the biasing of the device and it stands between the source and drain terminals. The voltage on the gate terminal controls the channel width.
• This IRF3710 MOSFET comes with extremely low ON resistance, making this device preferable for low drop switching applications. The low drop is responsible for low power loss, thus guarantees greater efficiency.
• The MOSFETs are termed the voltage-controlled device in opposed to bipolar junction transistors that are current-controlled devices and contain terminals emitter, base, and collector.

• The MOSFET works in two modes i.e. depletion mode and enhancement mode.
• And the behavior of electrons is different in both these modes. During the enhancement when there is no voltage across the gate terminal, there will be no current across the channel. While when voltage is applied across the gate terminal, the conductance of the device will increase.
• During depletion mode, however, when no voltage is applied across the gate terminal, there is conductance across the channel. While, when the voltage is applied, the channel conductivity will decrease.
• The MOSFETs are mainly divided into two main types i.e. P-channel MOSFET and N-channel MOSFET. The IRF2807 belongs to the N-channel MOSFET where conductance is carried out by the movement of electrons.

• This device is mainly used for fast switching applications and comes with ultra-low on-resistance of 0.55 Ohms which is the resistance between drain and source terminals.
• The IRF740 contains three terminals named source, drain, and gate. Sometimes it is termed as a four-pin device when the body is also considered as its terminal.

• The gate terminal is located between the source and drain terminals and is the area used for biasing of the device. While the drain terminal is the location from where electrons leave the channel and the source terminal is the location from where electrons enter the channel.

• The MOSFETs are mainly categorized into two main types named N-channel MOSFET and P-channel MOSFET. This device IRF740 belongs to the N-channel MOSFET where electrons are responsible for the current flow inside the device as opposed to P-channel MOSFETs where holes are the charge carriers responsible for conductance inside the device.

2SC1061 NPN Transistor Datasheet, Pinout, Features & Applications

Hello Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to 2SC1061.

2sc1601 is an NPN bipolar junction transistor used for switching and amplification purposes. During the amplification process, the small input current across one pair of terminals is used to generate a large output current across other pairs of terminals.

2sc1601 is known as a semiconductor device made of silicon material. This is a bipolar junction transistor where two charge carriers (electrons and holes) play an important role in the conductivity inside the transistor. As this is an NPN transistor so here major charge carriers are electrons while holes are the minority carriers.

I suggest you buckle up as I’ll detail the complete Introduction to 2SC1061 covering datasheet, pinout, features, and applications. Let’s dive in.

Introduction to 2SC1061

How to Determine What Wattage of Solar Panel I Need to Choose

Hello! I welcome you on the board. we'll talk about the Solar Panels and it wattage to choose the solar panel according to the need of time. The performance and efficiency of a home power plant directly depend on the correct choice of solar panel characteristics. Innovative technology has made it possible to create a record 400 watt solar panel, which is currently the most efficient and economical. To determine the number and capacity of solar panels, it is necessary to accurately calculate the total energy consumption and choose the right type of panel.

Choose the Type

To determine the number and capacity of solar panels, it is necessary to accurately calculate the total energy consumption and choose the right type of panel. There are 2 main types of solar panels:

1. MonoCrystalline.
2. PolyCrystalline.

MonoCrystalline panels have great performance but only work when exposed to sunlight at an angle of 90 degrees. It is more efficient to install them in large solar power plants, where high output is important.

Polycrystalline panels work at any angle of inclination of the sun but have lower productivity. This type of module is more suitable for installation at home since they have a lower automatic start threshold.

Define the Brand

If it is important to you that your solar panel works efficiently and for a long time, take a closer look at the manufacturer's brand. Choosing the right company will provide you with excellent product quality.

It is best to choose from the "Tier1" list. Here are the top manufacturers from all over the world. As of 2020, the leading companies were:

• Jinko
• LONGi
• Solar
• Risen
• Trina
• QSells
• Talesun
• Astronergy
• Jinergy
• LG

Calculate the Power After you have chosen the type and manufacturer of solar panels, you should proceed to the most important step - calculating the power. To do it, you need to know exactly how much power you are using. There are two ways to do this:

• Check data on meter readings (less accurate)
• Independently calculate all electrical appliances, their power, and operating time. This way, you can get the most accurate result.

Also, you need to add about 20-30% to the resulting value. This is the energy consumption of the inverter and the accumulator of the battery itself. After that, you need to look at the indicators of solar radiation for the required city. For example, this figure is 0.8 for winter and 5 for summer. For solar panels to operate at full capacity, it is important to receive direct sunlight at an angle of 90 degrees. This figure cannot be achieved throughout the day. Thus, solar panels can only function at 30-70%, depending on the region of location. Also, you should keep in mind that the panels produce energy only during daylight hours, which, in the summer period, are approximately from 8-9 a.m. to 4-5 p.m. In the autumn-spring and winter period, this number decreases significantly. The panels do not function at night but accumulate energy generated during the daytime.

Follow the Formula 

The formula for calculating the power of a solar panel looks like this: W = k*Pw*E.

• Where «k» is a fixed index – 0,5 in the summer period, and 0,7 in the winter period
• Pw – the power of a battery;
• E – solar radiation index for the selected period

If there is a 310-watt solar panel, and the solar radiation index is 0.8 for winter and 5 for summer, then W = 0,5*310*5 = 775 watt per hour in summer W = 0,7*310*0,8 = 174 watt per hour in winter For example, you have calculated the total energy consumption of your house and got 6,000 watts. Also, we have to add approximately 30%. So, we receive 6,000*1,3 = 7,800 watts.  Now, we have to divide the total energy consumption on the W index: 7,800/775 = 10; 7,800/174 = 45. So, to cover all your needs, you have to install 10 310-watt solar panels in summer and 45 in winter.  Thus, based on the results of calculations, you can independently adjust the area and power of solar panels. Everything depends on your needs and desires.

Client Invoice Tips: 10 Ways to Invoice Clients Better

Hello Reader! Welcome to The Engineering Projects. At the present time, we'll discuss about the client invoice and the tips and tricks to manage your client invoice service. We all know Payment matters are always a bit of an issue when it comes to ending up a deal. One way or another we all work to get a further reward and mostly it is about money. Usually, the system of client invoices is pretty much tuned. However, a certain need for better optimization from time to time pops its head up. To avoid extra stress you might want to look through the information below and get some inspiration on how to improve your invoice arrangements.

Comprehend the importance of an invoice

Invoices are meant to keep track of any business operation having place. This is your legal document that provides you with the  guarantees for the service being paid. At the same time, it backs you up when some financial issue arises from whatever side of the deal. Invoices are valuable when it comes to accounting matters. As an entrepreneur, you must get accustomed to operating them masterfully. 

Get professional design

With all the graphic design apps on the market to find a decent invoice maker will pose no problem at all. Turn to various templates that will arrange all the information required in a fine-looking, professional document. Place your signature, or special brand-stamp, that is recognizable for the client. With the templates chosen, customize other brand qualities - logos, color palettes, fonts etc. for an even more presentable look. Bigger companies have their invoices generated automatically, and they also care for the design.  It might seem as not the most essential part, since not the colors, but money on time matters, however even the design of your invoice is a part of your brand presentation. 

Mind client's requirements

?ompanies are usually overwhelmed with the number of invoices they get to process daily. There are chances that they might ask for a certain format of the invoice you send them. Therefore you might have to adjust your beautiful design with their requirements. This will demonstrate you being considerate of their concerns. Also, it ensures your invoice to be noticed and funded without delays and awkward reminders about your rewards. 

Define the person in charge

When discussing the payment matters make sure to talk to the right person or the right accounting department. You might want to avoid your invoice sent somewhere and get lost in the huddle of gazillion letters sent daily. Double-check right from the start of the negotiation of your services.  The way you are going to get informed about this matter may already tell you how responsibly the company, or the client treats this matter and what words are used specifically. Evasive tone and clear avoidance of the topic will help you think better about whether to get contracted for the job at all.  

Include payment deadlines

Make sure that your invoice contains exact information about the terms when you expect to get your funds. While discussing financial matters before the deal you may already announce your number expectations and how they should be delivered. However, it is never redundant to outline it in your invoice again. With the busy life everyone leads to keep all things in mind is not always a possible matter. The negotiated sum and the time when it is expected are the main figures that your invoice is developed around.

Create an invoice filing organization

It is highly recommended for better optimization and more order to create folders with various invoices sent to your clients. Arrange them by dates, names of the clients, terms of getting paid, those that are unpaid. Having a fine structure developed you will always be able to trace how things are going for you money-wise. This may be deprived of all the romantic flavor since you as the creator should not waste your energy on anything other than art and rewards are just pleasant bonuses...Now, when you have come back to earth, please take care of the filing system and your invoices being in ship-shape order. 

It is OK  to remind about unpaid invoice

When terms are outlined in a crystal clear manner, however, the customer’s side has not respected the commitments it is totally acceptable to send a follow-up email. Hectic business world intends to miss out on some aspects ( not cool, yet inevitable), your reminder will be appreciated and even an apology letter may loom upon the horizon. Other clients feel sad to part with their money, especially when the total amount is quite impressive. Such representatives need an extra push to deliver their end of the deal. Every job done should be rewarded, no excuses here. 

Ask for deposit 

Sometimes, in the matter of precautions, it is recommended that you ask for the deposit. Mostly the payment is delivered when the work is done and meets all the requirements. In order to avoid experiences when such highly-professional work goes unpaid, you may ask for some money paid beforehand. Your clients contacted you to get your services after they have checked through your profiles and your happy clients' testimonials. They know they can trust you in your expertise and follow the deadlines. You know that you can trust them when they freely agree to your deposit terms. Then there is a big chance to get the rest of the payment with no delays and unnecessary reminders.

Thank your clients

In comparison with all the critical matters, invoice-wise thanking might pale a bit. To get gratitude is always a pleasure. Running through hectic days, when everything that you just see are numbers, requests, and reminders, to get a thank you note for a change might make someone's day. Who knows, maybe after you will be placed in the category “Priority payment”.

Take it easy

It does not mean -  let it loose and see what the outcome might be. No, you keep on monitoring the financial side of the work you do. However, do not let yourself  get consumed utterly with accounting, since there is some other job that has to be performed, requiring your full devotion. There is always a way to divide and conquer.

To sum up

Let’s go over again. In order to get paid relatively quickly when invoicing the clients, you have to be ready to commit to creating a professional invoice with crystal-clear information about your services and payment expectations. Be precise, and indeed considerate in the discussions about funding matters. Create a fine filing system in order to be on the safe side always. Do not be afraid to ask for what it's worth, becoming a victim of those who are not used to paying for the services they got. When you are a rookie and gain experience it is quite normal practice to do some job for free, but being an experienced specialist with high-quality services requires money to be paid and exactly when you ask for that.

Top 5 Reasons a Survivalist Should Be an Amateur Radio Operator

Hello friends, I hope you all are doing great. In today's tutorial, I am going to share Top 5 Reasons a Survivalist Should Be an Amateur Radio Operator. With 2021 setting in, are you well prepared to survive if the world goes down? We live in uncertain times, and the pandemic has taught us that what we plan today might not be applicable tomorrow.

Currently, there are more than 700,000 license holders of amateur radios within the United States, and as ham radio sales increase rapidly during the current pandemic, you might be shocked to know that before social media platforms, such as Facebook, Twitter, etc., ham radio users were originally hailed as social media geeks. Ham radio operators have amazing technology incorporated within their radio sets, such as voice boosting satellites and Morse code messages. Ham radio operators consider themselves the ultimate survivalists as they have been using a social media platform that is more than a century old. When survivalists use am radios over the air, they keep the conversation respectful. By bouncing signals off the ionosphere, survivalists can reach around the globe with their ham radios. Also, when shit hits the fan, ham radio might be the only platform to communicate.

Replete With Emergency Related Options

A survivalist should be an amateur operator because it enables them to make an emergency autopatch and then activates the autopatch system. With the ham radio, a survivalist can learn how to report an incident quickly and clearly without assuming that other people might be doing it already for you. Since ham radios are replete with emergency-related options, you have to turn up the radio's output power to maximum and state "Break Emergency" at your first opportunity. Survivalists can also learn how to make a distress call on a certain frequency where ham radio operators are more likely to be listening.

Listen in on Emergency Responder Frequencies

Some ham radios can receive many frequencies outside of the ham bands, which include the frequency of emergency responders, such as the police department and rescue services. Some of the ham radios can listen in on emergency frequencies and transmit on those frequencies. Nonetheless, only one circumstance is perfectly legal for a ham radio operator to transmit on emergency responder frequencies, irrespective of whether they are licensed or not. The exceptional case refers to an immediate emergency when no other communication method is available, and you attempt to get assistance via proper ham radio.

Cost-Effective

If you are preparing for the post-apocalypse era, you should be concerned about effective communication while staying within a budget. Ham radios are known as the best-budget radio in the communication industry. It is a cost-effective and powerful gadget for wireless communication. This means that you won't have to break the bank to get an effective communication tool for the darkest hours on earth.

You Can Practice Your Ham Radio Skills

Ham radio hail from the earliest radio technology. If you have ever been remotely interested in radio technology and looking for the perfect survival gear, Ham radio can be your go-to gadget. Amateur radio operators often practice their radio skills and electronics while communicating through high-frequency ham bands. By combining radio with computers and other technologies, data and texts can be sent via radio-frequency.

How To Build the PCB Best - JLCPCB

Hello Professional! Welcome to The Engineering Projects. We hope you are having a productive day. Today we'll talk about the building process of Printed Circuit Board with great efficiency and creativity. It's hard-won to run an industrial company. What’s the reason? One is  the bosses who have earned money quickly expand their business footprint not only focus on PCB,  not delve into how to provide higher-quality PCB and more extreme customer service; also many bosses think more about engaging in financing and listing. How about JLCPCB?Yes, JLCPCB has planted into the PCB with all its heart, just keeping one aim: build the PCB best. JLCPCB was founded in 2006, used to be the leading PCB company, now it is PCB industry big brother, who is highly appreciated and trusted by hardware fields. When JLCPCB makes a mistake, people will say all they know  without reserve. If the proposes will benefit the PCB users, JLCPCB takes act upon it without reserve. All we believe 15 years could build such solid and close relationship between customer and merchants. All suggestions and feedback from customers about production efficiency, PCB quality, customer service and logistics situation will be valued by JLCPCB team. CEO Yuan was also a young electronic engineer before, and spent a lot of time in designing, developing, and testing components, devices and systems in a small PCB factory. Now he has grown up to be JLCPCB leader and is keen on optimizing and developing automatic production lines,  intelligent factory management and brand new SMT assembly methods. He knows how sad it is for an electronic engineer to lack a good and inexpensive PCB board. His regret will not become the regret of a new generation of electronic engineers, so he insists on the PCB industry for more than 20 years, insists on low price but high quality PCBs for customers, and strives for excellence in craftsmanship and customer service. $2 for 5 PCBs, and $7 Start SMT assembly.  Mr. Yuan elucidated, “The profit of the PCB industry is very transparent. Low price, superior quality, fast delivery. The essence is contradictory.” He added, “the only way to solve this contradiction: large production with the fully automated factory.”  Yes, PCBs with high quality, low-cost and quick logistics must reach a certain scale of production to earn profits, 100% true. JLCPCB  fully automated factory is indispensable. So far, it has 5 fully automated factories for 600,000 ? per month, 9 SMT production lines 12-hour fast assembly 35,000,000+ parts monthly. JLCPCB hopes to help engineers and companies to access most economic, best and innovative PCB service. We are trying to meet and exceed loyal users' expectations in price, service and production. Even in 2020, it made these new attempts:

• The SMT production plant was relocated  to an advanced factory, expanding from the previous 32 machines to 72 placement machines.
• expanded from the original 4 SMT production lines to 9 SMT production lines to support more production.
• Parts have increased from 30,000 kinds to more than 80,000 kinds.
• Added black, blue, red  PCB assembly service.

JLCPCB was also encountered many difficulties in Feb. 2020 because of the COVID-19 epidemic, which resulted in a bit longer PCB turnaround time and SMT order production delay. And the lead time has become as fast as before since March,2020. We redistributed the staff, and reorganized the equipment and manpower to make the production line run more and more smoothly. Of course, this is achieved when we ensure that our own employees are sufficient and well paid. That's why we always say methods are more than difficulties. Good products should be used by more people, especially people who desire high-standard  hardware.For foreign customers, the first impression of JLCPCB is "$2 for 5 PCB" which has successfully entered the customers' sight. People may curious about a "comprehensive JLCPCB" besides what they see online:where is the factory of JLCPCB ? What is the factory like? Who are the members of the JLCPCB team? Distance makes obstacles, however how JLCPCB shorten the distance with foreign customers.We would like to customize some small gifts randomly placed in the customer's boxes. As the boxes flow to all corners of the world, people will receive our greetings. Little gifts are always appreciated and collected by the friendly users. For customers JLCPCB is a strong backer , thoughtful and caring. For JLCPCB, they are creative and productive talent.Their hardware projects promote the development of technology and are also changing people's lifestyles and the pattern of the world. Equipping and optimizing is JLCPCB 2021 target. JLCPCB are going to increase  SMT part kinds, optimize the ordering process, and improve SMT quality while fastening turnaround time. In addition, it will add a 10,000 square meter plant with 100 SMT machines for small batch orders, also it can support double-sided SMT for any thickness. Every new attempt requires courage, and every “first” also requires more courage.JLCPCB, the first one to establish a fully automatic factory; the first to use the ERP system for online ordering; the first to cooperate with Alipay; the first to have ‘non-stop production in CNY holidays”. With a 15-year history, JLCPCB has taken every step steadily and will not waiver for any difficulties. JLCPCB believes building PCB best is the right way to gain customer retention. Chinese New Year holiday is around the corner. JLCPCB users know that we keep production on holidays, even during the Chinese New Year Holidays. Certainly we will be here to serve everyone,1&2 layers PCBs, SMT assembly and Stencil will keep producing. Better late than never, we wish everyone a happy new year, stay healthy!

IRF3710 MOSFET Datasheet, Pinout, Features & Applications

Hello Guys! Hope you’re well today. I welcome you on board. In this post today I’ll describe the Introduction to IRF3710.

The IRF3710 is an N-channel MOSFET made up using advanced process technology. It is mainly used for fast switching purposes and comes with extremely low on-resistance. It is a fully avalanche-rated device with a gate-source voltage of around 20V.

I suggest you read this entire post till the end as I’ll detail the complete Introduction to IRF3710 covering datasheet, pinout, features, and applications. Let’s jump right in.

Introduction to IRF3710

• The IRF3710 is an N-channel MOSFET mainly employed for fast-switching purposes.
• It is manufactured using advanced process technology and comes with very low on-resistance.
• This device is composed of three terminals a drain, gate, and source. Sometimes it is also called a four-terminal device where the body is also considered as the terminal of the device.
• The electrons enter the channel through the source terminal and they exit the channel through the drain terminal. While the gate terminal is used for biasing the device.

• The gate pin is located between the source and drain pin. The voltage on the gate pin is used to control the channel width.
• This IRF3710 MOSFET carries low ON resistance, making it a suitable pick for low drop switching applications. The low drop leads to low power loss, hence ensures greater efficiency.

• The MOSFETs are considered the voltage-controlled device in contrast to bipolar junction transistors that are current-controlled devices and comes with terminals base, emitter, and collector.
• The MOSFETs are mainly divided into two types i.e. N-channel MOSFET and P-channel MOSFET.
• This chip IRF3710 falls under the category of N-channel MOSFET where current is carried out by the movements of electrons as opposed to P-channel MOSFET where holes are the major charge carriers. The movement of holes is slow compared to the movement of electrons, making N-channel MOSFETs better than P-channel MOSFET for any electrical project.
• The MOSFET works in depletion mode and enhancement mode.
• During the enhancement when there is no voltage, there will be no current across the channel. While when voltage is applied across the gate terminal, it increases the conductance.
• During depletion mode, on the other hand, when no voltage is applied across the gate terminal, there is current across the channel. However, when the voltage is applied across the gate terminal, it will decrease the channel conductivity.

4 Things Every Modern Office Needs

Hey Readers! I welcome you on the board. I hope you are doing Great. are you establishing a new office? or you want creative ideas about your Office? or you just want to get the concepts about the Modern office requirement? then I can help you. Office designs continue to change with modern trends, and there are many aspects of office design that can even have an impact on the productivity of the people who work there.  It is more important than ever that the office environment is a welcoming one to ensure that every staff member will be able to give their best in terms of collaboration and work, and there are a number of things that every modern office needs - everything from spatial design to using LED strip lights. A varied and comfortable workspace Young professionals tend to enjoy a modern open floor plan in the office. Collaboration and communication are important and a modern office needs to promote this. However, there can be too much of a good thing and it is still important that employees have a place in which they are able to concentrate by themselves or within smaller groups. A modern office should provide space for these more intimate activities, or the segment of the workforce that may need quiet in order to get things done could be alienated.  A modern office should provide the space to allow these activities to be undertaken simultaneously, allowing employees to move between activities as required without distracting others.  Appearance and lighting In addition to the way in which a modern office is laid out, how it looks and how it is lit is also of vast importance to employee comfort and productivity.  It is a scientific fact that our mood is dictated by our environment, and colors play a big role in this. The modern office should be painted in a color that has a calming and relaxing effect, and wall accessories and throw pillows can also be made use of to create a positive atmosphere.  Lighting is also of key importance to offices, and the trend in modern offices is to make use of LED strip lights over the more traditional fluorescent lighting. In addition to being more environmentally friendly and cost-effective, LED strip lights have also been shown to be more beneficial to the health of office workers, improving mood and vitality, where mental issues such as stress can be caused by poor lighting.  Access to technology  The modern office needs to be equipped to deal with all aspects of modern technology. Modern offices try to allow employees to work wherever they like, which means they need to be able to gain access to their data wherever they want. This means that a strong Wi-Fi signal needs to be available at every point in the office, with lots of Ethernet ports throughout the environment as well as wireless charging solutions, recessed power outlets in tables and desks, Bluetooth headsets, cordless phones and cords in floors, trays and walls.  Socialization and health A common area or lounge is a good way to help with office socialization. The area needs to be relaxing and away from the main office to allow for conversations without distracting others. Some modern workplaces even provide a gym or wellness room where employees can keep fit, and the pantry should be stocked with healthy snacks.  Workers spend a good deal of their lives in the office, making it essential for the modern office to ensure their health and happiness. A healthy and happy employee is a productive employee.
