(In-Cabin Air Quality Monitor)

Air Conditioning

By monitoring in-cabin CO2 concentration with a sensor and setting optimal ventilation conditions, you can reduce the risk of drowsiness and maintain a comfortable in-cabin environment.
In addition, by optimally controlling the air conditioner and reducing power consumption, it is expected to improve fuel economy and battery life.

AKM's NDIR type CO2 sensor chip set can compose a compact and low power consumption CO2 sensor by adding microcomputer.
