With the DHT22, the DHT11 sensor is the basic sensor used in most Arduino, ESP8266 and Raspberry Pi tutorials. It is very economical and allows for very simple practical measurements of its environment. This tutorial explains how to measure temperature and humidity using the DHT11 with Arduino code or the ESPEasy firmware. Find all the examples and projects made with ESP Easy here.
Technical characteristics of DHT11
