In this ESP32 tutorial, we will check how to get measurements from a C02 sensor, using the Arduino core. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board. Advertisements
In this tutorial, we will check how we can get humidity measurements from a DHT22 sensor, with the Arduino core running on the ESP32. To make the interaction with the sensor easier, I’m using a DFRobot DHT22 module which has all the additional … Continue reading
The objective of this post is to describe a cheap rain sensor that can be used to detect rain with microcontrollers such as the Arduino or the ESP8266.
The objective of this post is to show how to connect the DHT11 sensor to an ESP8266 and write a simple program to measure temperature and humidity. We assume the use of the Arduino IDE for programming the ESP8266.
