Create Your Own CO Detector - Digi-Key

Building a CO (carbon monoxide) detector that can alert you to dangerous levels of CO can be done with as little as a gas sensor, an Arduino (or other microcontroller) and some resistors. Adding a few op-amps can boost the sensitivity to measure the amount of CO present in the environment. Expanding on this knowledge, you can build your own air quality monitoring station, and compare your own ...

CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.

Identifying poorly ventilated areas and using CO2 monitors

CO2 levels vary within an indoor space. It’s best to place CO2 monitors at head height and away from windows, doors, or air supply openings. Monitors should also be positioned at least 50cm away from people as their exhaled breath contains CO2. If your monitors are too close they may give a misleadingly high reading. Measurements within a space can vary during the day due to changes in ...
