It is a small box that houses the sensor DHT22 and the uC ESP32 for it, it also includes an OLED screen that shows the temperature and relative humidity, it also includes the 18650 battery with its respective charge controller and also allows IoT mode.Download...
I've been trying to make a temperature sensor based on the ESP32-C3-DevKitM-1 and using a driver from GitHub. I already tried 2 and both timeout trying to read from the sensor. Once I plug it into an Arduino, with the same pin configuration, it works....
Learn how to fix the Failed to read from DHT sensor error. If you need further help, please post a new question here:https://rntlab.com/ask-question/ Thanks! P.S. Learn more about the ESP32 or ESP8266 GPIOs below:
values. I wanted to combine all interesting functions into one library. In addition, none of the DHT libraries I found were written to work without errors on the ESP32. For ESP32 (a multi core/ multi processing SOC) task switching must be disabled while reading data from the sensor. ...
