Seeed Studio Grove Multichannel Gas Sensor V2

A Grove module from Seeed Studio with 4 different gas sensors. The module has a microcontroller that reads the 4 sensors. This microcontroller then communicates this data with an external microcontroller via I2C. The sensors cannot measure an exact concentration, but they can detect concentration differences over time.
