48 Hours with a CO2 Meter Aranet

Jan 05, 2021· Upon arrival at the apartment, the meter shoots from 623 to 1682 ppm in a matter of 15 minutes. The windows are closed and the heat is on. After turning off the heating and opening two opposite windows for ventilation, the carbon dioxide concentration drops back below 800 ppm. An hour later it is at 585 ppm.

The Benefits of Energy Efficient NDIR Gas Sensors

Jun 19, 2019· NDIR technologies are very popular in gas sensors as many common gases, absorb light very strongly in the infrared region of the electromagnetic spectrum. This means that using a coupled IR source and detector, it is possible to measure even low concentrations of these gases with realtime online monitoring. MIPEX optical gas sensor technology.

Overview | Adafruit SCD30 NDIR CO2 Temperature and ...

Jan 06, 2021· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) 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 ...
