PIM486 Enviro: HAT for Raspberry Pi turns the single-board computer into a smart home sensor with a display

Pimoroni has designed the PIM486 Enviro for environmental monitoring and markets the HAT as the "perfect way to get started with citizen science". The PIM486 Enviro is compatible with all 40-pin Raspberry Pi modules, while Pimoroni has published a Python library for the HAT on GitHub.

The PIM486 Enviro is a pHAT format board that measures 65 x 30 x 8.5 mm. Pimoroni has integrated humidity, temperature and pressure via its BME280 sensor, along with light and proximity using an LTR-559. There is also a MICS6814 analogue gas sensor, an ADS1015 analogue to digital converter and a MEMS microphone. Pimoroni provides datasheets for all these sensors, for reference.

There is a 0.96-inch LCD panel too, which operates at 160 x 80 pixels. Incidentally, Pimoroni states the board can send data to be viewed remotely. The PIM486 Enviro retails for US$28.52. The company sells the PIM458, which can measure air quality, for US$49.60 too.
