In some cases, you might need to power your board with a power source that provides more current. Power sourceĪs mentioned in the previous tip, your board (ESP32, ESP8266, Arduino, etc) might not be supplying enough power to properly read from the DHT sensor. Having a USB port that supplies enough power or using a good USB cable often fixes this problem. It might also help replacing the USB cable with a better or shorter one. Try to plug it to a USB hub powered by an external power source. Sometimes powering the ESP32, ESP8266, Arduino or similar boards directly from a PC USB port is not enough. If you’re powering the sensor from a 3.3V pin, in some cases powering the DHT with 5V solves the problem. The DHT sensor has an operating range of 3V to 5.5V (DHT11) or 3V to 6V (DHT22). After checking and testing that your circuit is properly connected, if it still doesn’t work, continue reading the next troubleshooting tips. When you’re building an electronics project, you need to double-check the wiring or pin assignment. Try one of the next troubleshooting tips.
