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

I bought a pair of these. They went to the Raspberry Pi 3 with Buster and the older Raspberry Pi 2 with Wheezy. This DHT22 comes with a resistor already installed, so you only need 3 pins: VCC, ground, and data. The setup for Buster is quite simple. Just make sure you have python3 installed and pip3 installs the Adafruit library. For Wheezy, installing pip3 is a chore, skip it and instead just clone the Adafruit library and use their standard Python sample code to make it work. Both sensors seem to track fairly accurately and the difference is very small. between temperature and humidity measurements. I've been working with them for a day now and so far I'm very happy with the results.
