DHT PinoutDHT sensors have four pins as shown in the following figure. However, if you get your DHT sensor in a breakout board, it comes with only three pins and with an internal pull-up resistor on pin 2.The following table shows the DHT22 and DHT11 pinout. When the sensor is ...
(This schematic uses the ESP32 DEVKIT V1 module version with 36 GPIOs – if you’re using another model, please check the pinout for the board you’re using.)Note: if you’re using a module with a DHT sensor, it normally comes with only three pins. The pins should be labeled so ...
