I had nothing but problems with DHT22/AM2302. most of the python scripts and instructions were deprecated I now use the SHTC3 Temperature Humidity Sensor Module with any raspberry pi. I followed this guide for the raspberry pi https://cdn-learn.adafruit.com/downloads/pdf/adafruit-sensirion-shtc3-temperature-humidity-sensor.pdf https://cdn-learn.adafruit.com/downloads/pdf/adafruit-sensir... enable i2c on the pi. ssh into the pi create an alias to start it.

DHT22 isn't too bad (and certainly more accurate than the DHT11), and even though it's slow, it seems fine for the OP's use case. Personally, I like the HDC3021. It's I2C, uses different addresses for different sample rates, high accuracy and precision, and has a built-in heater so your code can command it to cook off condensation if dew points are high. It's also more expensive, but man, it's a robust component.
