VOC Sensor Capabilities and Limitations - Application Note ...

A VOC sensor informed ventilation system can optimize indoor air quality while minimizing energy use. There are over 5,000 VOCs that are expelled by breathing, cooking, bodily functions, perfumes, deodorants, paint, cleaners, cigarettes, office supplies, etc. BAPI’s VOC sensor monitors these gases and provides a CO2 equivalent ppm (parts per million) output which is then input to a DCV system.

Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

2021-07-25· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Gas Sensor | HVAC Systems | Manufacturer

2019-01-08· 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 ...
