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.
