Dual Beam NDIR CO2 Sensor

CM1107N is a dual beam (single light source, dual channel) CO2 sensor, based on non-dispersive infrared (NDIR) technology, which can detect CO2 concentration of indoor air. With higher accuracy, superior long term stability, it is widely used for ventilation system, air purifier, air conditioner, intelligent agriculture, storage and cold-chain, etc
