Low Power NDIR CO2 Sensor
CM1106LSCM1106LS

Low power with working current 35mA, CM1106LS is a single beam NDIR CO2 sensor module, based on non-dispersive infrared (NDIR) technology, which can detect CO2 concentration of indoor air. With ABC open by default, and no need of maintaince. With high accuracy, high stability, small size, it is widely used for ventilation system, air purifier, air conditioner, HVAC transmitter, IAQ monitor, etc.

Note 1: In normal IAQ applications, accuracy is defined after minimum three (3) ABC periods of continuous operation with ABC on. Some industrial applications do require maintenance. Contact Cubic for further information.

Note 2: Specification is referenced to certified calibration mixtures. Uncertainty of calibration gas mixtures (±2% currently) is to be added to the specified accuracy for absolute measurement.
