Показать описание
This video will be a walkthrough on how you can use DHT22 with Arduino to measure temperature and humidity to make projects like thermostats. This video introduces you to the basics of DHT22, and how to program to communicate with it, whether by using / not using external libraries. This can be a helpful start before learning about more advanced communication protocols in IOT.
