CO2 sensor is to detect CO2 present in the air by using the principle of non-dispersive infrared (NDIR), which closely combines the mature infrared absorption gas detection technology with precision optical circuit design and refined circuit design, and has a built-in temperature sensor for temperature compensation, with good selectivity, no oxygen dependence and long service life.

(1) High sensitivity and high resolution.

(2) Low power consumption.

(3) Temperature compensation.

(4) Excellent stability.

(5) Long service life.

It can be widely used in HVACR and indoor air quality monitoring, industrial process and safety protection monitoring, small weather stations, agricultural greenhouse sheds, environmental rooms, grain stores, breeding, flower breeding, commercial building control, office buildings, schools, conference rooms, shopping malls, restaurants, gymnasiums, cinemas and monitoring of CO2 concentration in the production process of animal husbandry.
