Now that you can connect your Raspberry Pi Zero to campus Wifi, what to do with it? How about a simple cloud-connected temperature and humidity sensor? For this project, I combined a Raspberry Pi Zero W with a DHT22 sensor. The DHT22 is a cheap, widely available sensor that can measure temperature with an accuracy of ~0.5 °C and humidity with an accuracy of ~5%. You can read about the DHT22 in wonderful detail here.
