CO2 sensor, added safety on the road
LAC52 has built-in CO2 sensor.When the carbon dioxide level in the car exceeds the alarm limit, the buzzer in the main unit will give different levels of alarm. (The alarm will start when the car's carbon dioxide level exceeds 2000PPM, 2500PPM, 3000PPM) Elevated CO2 levels cause drowsiness so this will remind the driver to get fresh air.
