Hi Blynkers, I tried several times but my esp8266 doesnt work with dht22, I check that dht works fine with and arduino and I also check that my esp8266 works fine with a ultrasonic sensor, but doesnt work esp8266 and dht.

Arduino Playground - DHT11Lib

The DHT11 is a relatively cheap sensor for measuring temperature and humidity. This article describes a small library for reading both from the sensor. The DHT22 is similar to the DHT11 and has greater accuracy. However, this library is not suitable for the DHT21 or …
