Project for humidity and temperature datalogger using DHT22 sensor.
For this project we'll use the following hardware:
- a RaspberryPi Zero W computer (should work on any RaspberryPi);
- a DHT22 humidity and temperature sensor with PCB (which allows us to avoid soldering the 10 kΩ pullup resistor required);
- a powerbank to power the RaspberryPi outdoor.
