The tests were performed using a DFRobot’sESP32 moduleintegrated in aESP32 development boardand awaterproof versionof the sensor. The code We will start our code by including the needed libraries. The first one is theOneWire.h, which allows to interact with devices using theOneWireprotocol....
Zigbee examples got updated to work with latest esp-zigbee-sdk. Also 2 new examples have been added to work together: Temperature sensor (End device) Thermostat (Coordinator) Everything mentioned is included in the latest release 3.0.0-rc3. ...
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 the sensor suports. We are going to usethislibrary to interact with the DHT22 from the ESP32, using the ...
