AirTest Self Calibrating CO2 Sensor Explained

allowing the light to bounce around many times in the optical sensor an extended sampling path can be compressed into a small package. For example, the small oval optical sensor used on the AirTest CO2 sensor measures less than 1” by 2” yet it can travel a path through inches of CO2 before it reaches the detector. This offers a significant benefit over traditional straight path sensors ...

CO2 (carbon dioxide) Zigbee sensor | DIY zigbee devices

The advantage of Automatic Baseline Calibration (ABC), is that the CO2 sensor is self-calibrating over the life of the sensor, and the sensor is able to gradually make a correction to compensate for the change. This means, for the end user you have a reliable and efficient method and also have a way to compensate for sensor drift in IAQ applications.

Where are the oxygen sensors located

You can reset the light by removing the "NEG" cable from the battery for a minimum of 5 minutes. Alternatively, the light will reset itself after roughly 50-75 miles of combined city/highway driving. Also, most local "big chain" parts stores, like AutoZone, will reset the light for Free (except in CA) right in their parking lot. If the light is to return, then the problem was not an Oxygen ...
