DHT22 Pinout Where to use DHT11 and DHT22 Sensors TheDHT11andDHT22are commonly used Temperature and humidity sensors. The sensor comes with a dedicated NTC to measure temperature and an8-bit microcontrollerto output the values of temperature and humidity as serial data. The sensor is also fact...
We have two versions of the DHT sensor, they look a bit similar and have the same pinout, but have different characteristics. Here are the specs: DHT11 Ultra low cost 3 to 5V power and I/O 2.5mA max current use during conversion (while requesting data) ...
