Gas Sensor | HVAC Systems | Manufacturer

· The most common gas sensors used in HVAC systems are oxygen (O 2) and carbon dioxide (CO 2) sensors. Ambient air is comprised of roughly 21% O 2 and just % CO 2, but a lack of indoor air circulation can dramatically skew the gas composition towards O 2 depletion and CO 2 enrichment. Indoor air quality (IAQ) is a critical factor for our ...

Wie funktioniert ein CO2Sensor?

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. The IR light detector measures the amount of IR light that passes ...

Testing the MHZ19 Infrared CO2 Sensor Module • Circuits

· Introduction: In this article we will do a simple functional test of the MHZ19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.

How Carbon Monoxide Detectors Work | HowStuffWorks

­CO detectors can use several types of sensors to sense carbon monoxide in the air. Biomimetic sensor technology reproduces CO''s effects on hemoglobin in the blood. In a biomimetic sensor, a gel changes color as it absorbs CO. A separate sensor detects the c­olor change and alerts the detector''s processor to sound the alarm. Once a biomimetic ...
