Description
An air quality measurement board to be used as HAT on top of the Raspberry Pi B+.
It should be easy to use thanks to the on-board labeling of all headers.
It can measure air...
- temperature
- humidity
- pressure (via BMP180 module board "GY-68" or compatible)
- and volatile organic compounds (VOC) via four MQ gas sensor slots of your choice
Additionally it can drive WS1812B LEDs (aka "NeoPixels") and exposes a couple of useful bus systems (spi/i2c/1wire) via headers.
