Web23 Sep 2024 · DHT11/DHT22 Interfacing with ESP32. Connect the DHT11/DHT22 to ESP32 along with a 10K ohm pull-up resistor. The connection diagrams are shown in the pictures below. DHT22 Interfacing with ESP32. The first pin for both sensors is a power supply (Vcc) pin. Connect it with the 3.3 volt pin of ESP32. WebConnecting a DHT11/DHT22 sensor to an ESP32 is pretty easy. Begin by placing the ESP32 on your breadboard, making sure that each side of the board is on a different side of the breadboard. Place the sensor on your breadboard next to the ESP32. Connect the sensor’s VCC pin to the ESP32’s 3.3V pin and ground to ground.
