We are familiar with multiple features of the ESP32 module. Like Wi-Fi capabilities, classic Bluetooth, Bluetooth low energy (BLE), inbuilt sensors etc. Hello readers, I hope you all are doing great. We have already mentioned in our previous tutorials that, ESP32 is also featured with a Dual-Core Processor. Which provides better performance and efficiency. In this tutorial, we will learn how to use ESP32’s dual cores. ESP32 has two (32-bit each) Tensilica Xtensa LX6 microprocessors namely, core0 and core1 which makes it a powerful dual-core microcontroller and hence stands apart from its pred ...

Hello readers, I hope you all are doing great. In our previous tutorial, we learnt how to make HTTP POST from ESP32 to the IFTTT server. In this tutorial, we will learn about another application of the ESP32 module in the field of IoT (Internet of Things). We can publish multiple sensor readings from ESP32 to Google sheets via the IFTTT web service. IFTTT is used as a third-party web service to integrate Google sheets with ESP32. Fig. 1 Creating an IFTTT Account for Integrating ESP32 with Google Sheets We are going to create an applet (on the IFTTT server) that is responsible to integrate t ...

ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on another ESP32 application in the field of IoT. Hello readers, I hope you all are doing great. In the previous tutorial, we learned how to send sensor readings from ESP32 to the cloud (ThingSpeak webserver). In this tutorial, we will learn to send HTTP POST requests from the ESP32 board to ThingSpeak and IFTTT APIs. What is HTTP? Fig. 1 Hypertext Transfer Protocol HTTP stands for hypertext transfer control and it is a protocol for transferring data between a web client and a web server. Hyper text tr ...

The Internet of Things ( or IoT) is a network of interconnected computing devices such as digital machines, automobiles with built-in sensors, or humans with unique identifiers and the ability to communicate data over a network without human intervention. Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send sensor readings from ESP32 to the ThingSpeak cloud. Here we will use the ESP32’s internal sensor like hall-effect sensor and temperature sensor to observe the data and then will share that data cloud. What is ThingSpeak? Fig. 1: ESP32 ThingSpeak It is ...

Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity. What is ESP-NOW Protocol? Fig. 1: ESP-NOW Protocol ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif. Features of ESP-NOW Protocol: It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using W ...

Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor. ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B2 ...
