This air quality sensor quickly and precisely detects the carbon dioxide content in the air, using an infrared system. It then signals how stuffy the air is, using both pictograms of faces and colour signals to do so. A green light signifies good air quality (up to 1,500ppm CO2), a yellow light indicates medium air quality (1,500 - 2,500ppm CO2) and a red light signals bad air quality (more than 2,500 ppm CO2). Additionally, acoustic signals indicate any changes in the air quality. The air quality signal is maintenance-free.
