You can find more information on the Datasheet


The CozIR®️-LP series 2 is a set of low power NDIR CO2 sensors 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®️-LP series 2 low power consumption is compatible with battery powered operation, allowing the sensor to be used in a wide variety of applications including wirelessly connected equipment.

The CozIR®️-LP series 2 operation is configurable depending on user requirements. Depending on type they can be set to stream data or for the ultimate in power saving can be set to take readings at intervals and consume no power between measurements.

The CozIR®️-LP series 2 also features a built-in auto-zero function that maintains CO2 measurement accuracy over the lifetime of the product.
