Monitor your world with Pimoroni's Enviro PHAT for Raspberry Pi! There are a whole bunch of fancy environmental sensors on these boards, and a gorgeous little full-color LCD to display your data. It's the perfect way to get started with citizen science and environmental monitoring - with a great UI and easy-to-use Python code
Enviro is designed for indoor monitoring, letting you measure temperature, pressure, humidity, light, and noise level. It's great for keeping tabs on what's going on in various rooms in your house, office, or elsewhere. Push the data to server, and you can view the data remotely from anywhere.
