WebApr 21, 2024 · Make sure you connected the DHT the right way and initialized. DTH11 Pin1 --> 5v and 10k ohm resistor Pin2 --> Arduino Pin7 and 10k ohm resistor Pin3 --> no connection Pin4 --> Gnd. I checked and it is telling me it that it cant read from the sensor. I beginning to think that this might be a hardware malfunction. WebThe DHT-22 (also named as AM2302) is a digital-output relative humidity and temperature sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin. In this tutorial you will learn how to use this sensor with Arduino uno. The room temperature & humidity will be ...
