In this ESP32 tutorial we will check how to develop a HTTP web server that will expose an API for clients to retrieve measurements of temperature, humidity and CO2, using a CO2 sensor and a DHT22 temperature and humidity sensor. The … Continue reading
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 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.
