In this guide, you’ll learn how to send sensor readings with the ESP32 to ThingSpeak. For demonstration purposes, we’ll use a BME280 sensor<\/a>, but you can easily modify the examples to use any other sensor. The ESP32 board will be programmed using the Arduino core.<\/p>\n\n\n\n

\"ESP32<\/figure><\/div>\n\n\n\n

ThingSpeak allows you to publish your sensor readings to their website and plot them in charts with timestamps. Then, you can access your readings from anywhere in the world.<\/p>\n\n\n\n

We have a similar tutorial for the ESP8266 board: ESP8266 NodeMCU Publish Sensor Readings to ThingSpeak (easiest way)<\/a><\/p>\n\n\n\n

Project Overview<\/h2>\n\n\n\n

There are many ways to send sensor readings to ThingSpeak. In this tutorial, we’ll use one of the easiest ways\u2014using the thingspeak-arduino library<\/a>. This library provides methods to easily publish sensor readings to single fields or multiple fields. You can check the library examples on its GitHub page.<\/p>\n\n\n\n

To exemplify, we’ll use the BME280 sensor, but you can use any other sensor (you need to modify the code). <\/p>\n\n\n\n

Recommended reading: ESP32 with BME280 Sensor using Arduino IDE (Pressure, Temperature, Humidity)<\/a>.<\/p>\n\n\n\n

We’ll cover how to publish to a single field<\/a> and how to publish to multiple fields<\/a>.<\/p>\n\n\n\n

Preparing Arduino IDE<\/h2>\n\n\n\n

For this tutorial we’ll program the ESP32 using the Arduino core. So, make sure you have the ESP32 add-on installed in your Arduino IDE:<\/p>\n\n\n\n
