ESP32 Arduino: DHT22 Minimum Sampling Period

In this tutorial we will check how to get the minimum sampling period of the DHT22 and how to use it to make some temperature measurements without crossing the maximum sampling rate. To facilitate the interaction with the sensor, I’m using … Continue reading

ESP32 Arduino: Getting temperature from a DHT22 sensor

In this ESP32 tutorial, we will check how to get temperature measurements on the Arduino core running on the ESP32, using a DHT22 temperature and humidity sensor. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
