Review on 🌡️ 2PCS HiLetgo DHT22/AM2302 Digital Temperature and Humidity Sensor Module - Arduino Compatible Temperature Humidity Monitor Sensor, Suitable for DIY Electronic Projects by Josue Zepeda

This is not really a project, but a plug and play device. I use it to measure and log the temperature and humidity in my office. Can anyone tell why to do this? A few thoughts come to mind. First, it gives you some basic Raspberry PI experience aside from flashing the lights. The information gathered led me to the conclusion that outside air was going straight into the intake of my HVAC fan. This led to overwork of the compressor and an increase in humidity in the room. So I think it's a good diagnostic tool.
