· IR Sensors. IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter. Higher CO2 levels would cause fewer IR rays to pass through the filter and be detected by the sensor. Low CO2 …

CO2 Gas Sensor User Manual – Vernier

Because the sensor operates on the basis of reading IR radiation, you should avoid using the sensor in direct sunlight as much as possible. Even though the IR detector is shielded, it is best to avoid the possibility of reflected light affecting the readings by keeping the sensor in the shade when used outdoors. Best results are obtained when only one CO 2 Gas Sensor is connected to an ...
