UltraLowPower CO2 Sensors Enable Wireless Remote ...

A wireless CO2 sensor suitable for use in IAQ systems consists of four major building blocks, a CO2 sensor, microcontroller, low power radio module, and a power source. Nondispersive infrared CO2 sensors work by illuminating the gas using a filtered incandescent light source and measuring the absorption using a light detector.


Lifebreath | Premium Indoor Air Quality Systems

Your home was built to be energy efficient, and Lifebreath’s HRV helps it stay that way. In winter, the HRV’s patented aluminum core transfers heat from outgoing, stale air to incoming fresh air so that it doesn’t need to be fully reheated. In summer, the HRV works in reverse, removing heat from incoming air, helping your home stay cool.


How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.
