Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

Jan 06, 2021· 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 ...

NDIR Gas Sensors - Electrical Optical Components, Inc.

An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not pre-filtered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using ...
