With the DHT11, the DHT22 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 DHT22 with Arduino code or the ESPEasy firmware. Find all the examples and projects made with ESP Easy here.

Technical characteristics of DHT22

  • Temperature measuring range: -40°C to +80°C
  • Measuring accuracy: +/- 0.5°C
  • Range of humidity measurement: 0 to 100% RH
  • Measurement accuracy: +/- 2%
  • Supply voltage: 3.3 to 5V (no impact on the measurement)
  • PWM digital output
