IRC-A1 Infrared Carbon Dioxide (CO2) Sensor Description
Alphasense CO2 and Methane infrared sensors are supplied in the industry standard miniature (20mm diameter) gas sensor housing.

Patented optics give the best signal to noise ratio of any 20mm diameter NDIR and universal linearisation constants allow easy implementation.

The on-board temperature sensor allows for software compensation, including ideal gas law correction.

The IRC-A1 with dual channel pyroelectric detector. This CO2 sensor is designed for IAQ, safety, combustion and high CO2 process control applications.

Application notes explain linearisation, temperature compensation and circuitry.

The IRC-A1 cover the entire concentration range of measurement, simply implement the appropriate linearisation constants in software for your required range:

IAQ 0 to 5,000ppm CO2
Safety 0 to 5% CO2
Combustion 0 to 20% CO2
Process control 0 to 100% CO2
