20190524· Even a "leaky" building with a bedroom door closed will have your carbon dioxide levels go above a safe level. (2,500ppm is not uncommon for a bedroom with the door closed.) Reading some studies and testing my own room, this became apparent to me. "But generally, while you should use CO2 level to increase ventilation, you should not use acceptable CO2 levels to reduce ventilation below …

The ability to handle the ventilation and evacuation setpoints, and everything in between, make the 03% CO2 sensor the best sensor for process leak detection. Mounting your CO2 sensor: The recommended method for mounting CO2 sensors in a process leak detection system is to mount them in the breathing zone (~5 feet off of the floor).

20210609· NDIR stands for Non Dispersive Infrared radiation and the carbon dioxide (CO2) sensors are based on NDIR technology. This technique is widely used to detect carbonbased gases such as CO2 that are present in the air. The CO2 gas enters the sensor and light from the Infrared (IF) source falls on CO2 molecules. These molecules absorb some amount of light at a wavelength of µm. This ...
