WHITECUBE

The Whitecube is a small home indoor air meter. The device measures room temperature, humidity and general gas condition (ppm). The Whitecube's MQ-2 sensor can detect LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations ranging from 200 to 10000 ppm. ppm mean Parts-per-million and it is the most commonly used unit for measuring gas concentration. ppm is simply the ratio of one gas to another.

The device is connected to the Arduino cloud, which can also be used to monitor the quality of the room air via e.g. a smartphone. The red LED indicates if one of the limit values has been exceeded.
