The Enviro+ is a pHAT extension board the size of a Raspberry Pi Zero designed for environmental monitoring. The board works with all editions of the Raspberry Pi and connects via a 40-pin GPIO.
The board itself has numerous sensors for collecting environmental data. Specifically, Pimoroni has included a BME280 sensor for measuring air temperature, humidity and pressure, an LTR-559 light and proximity sensor, a MICS6814 analog gas sensor and an ADS1015 analog to digital converter (ADC). There is a MEMS microphone too. Pimoroni has included datasheet for all the above sensors, for reference. You can find these on the Enviro+ product page.
Pimoroni has created a Python library for getting the Enviro+ working and an example of how to contribute to big data projects like Luftdaten. The data are both accessible via a corresponding Python Library, which should make the storage and processing of information particularly easy. You can also display the data captured on the 0.96-inch 160 x 80 colour LED display.
The Enviro+ is suitable for monitoring indoors and outdoors. Pimoroni states that it will be shortly publishing a tutorial to build an Enviro+ water-proof housing should you wish to leave it outdoors. The board currently costs US$47.63 and will ship worldwide from July 5.
