APPARATUS FOR MEASURING CONCENTRATION OF CO2 FOR VEHICLE

摘要

PURPOSE: A device for measuring the concentration of CO2 in a vehicle indoor space is provided to make an optical passage and an air inflow passage perpendicular to each other, thereby accurately measuring the concentration of CO2. CONSTITUTION: A device for measuring the concentration of CO2 in a vehicle indoor space comprises a vehicle indoor panel(B) and a CO2 sensor(100). The panel includes an air inlet. The CO2 sensor, which is installed inside the indoor panel, includes a light emitting unit, a light receiving unit, and a reflective film. The air flowing through the inlet flows perpendicularly in a plane where lights move.
