[SOLVED] DHT11/DHT22 – Failed to read from DHT sensor
WebPower: the DHT sensor has an operating range of 3V to 5.5V (DHT11) or 3V to 6V (DHT22). If you’re powering the sensor from the ESP32 3.3V pin, in some cases powering the DHT with 5V solves the problem. Bad USB port or USB cable: sometimes powering the ESP32 directly from a PC USB port is not enough. WebA tag already exists with the provided branch name.
