Dht with nodemcu
WebAug 21, 2024 · (Last Updated On: December 7, 2024) In this NodeMCU (ESP8266) Tutorial, I will tell you how to use the DHT11 or the DHT22 sensor for measuring temperature and humidity with the NodeMCU … Webdht.read () ¶. Reads all kinds of DHT sensors, including DHT11, 21, 22, 33, 44 humidity temperature combo sensor. Returns correct readout except for DHT12 and negative temperatures by DHT11. Use dht.read12 () and dht.read11 () instead. It is to use model specific read function anyway.
