CozIR®-LP2 CO2 Sensor

Designed for measuring low levels of CO₂, this miniature, lightweight sensor offers easy integration into gas monitoring and detection systems. This sensor is perfect for IAQ, DCV and HVAC applications.


The CozIR®-LP2 is an ultra-low power NDIR CO₂ sensor using state-of-the-art solid-state LED optical technology. The low-power LEDs are manufactured in-house, giving GSS complete control of the CO₂ sensor signal chain.

The CozIR®-LP2 allows users to reduce power consumption whilst maintaining high CO₂ measurement accuracy. The sensor incorporates a number of power saving modes, capable of reducing active and quiescent current consumption to unrivalled low levels.

The CozIR®-LP2 also features a built-in auto-calibration function that maintains CO₂ measurement accuracy over the lifetime of the product.
