Indoor air quality accessory

It detects carbon dioxide, temperature and humidity, and uses light signals to guide people to a healthy space. The sensor can also be programmed to detect other gases, movement, sound, and the amount of light.

Resembling a sailing boat, the monitor, which is based on IoT technology, uses comfort light signals to guide people if, for example, carbon dioxide levels in a room become too high. LEDs of different colours indicate when the level of gas measured by the sensor exceeds a certain threshold.

"The light changes from green to amber to red as the level of gas increases, and vice versa when it drops," senior scientist Markus Tuomikoski from VTT said. 

VTT’s Tiny Node platform can also be used to monitor the indoor air quality remotely and to communicate with other similar IoT devices.
