CO2 sensors - Sentera

Sentera CO2 NDIR sensors transmit the measured values into an analogue output or a Modbus RTU register. The algorithm of the intelligent sensors controls a single analogue output based on the measured temperature, relative humidityh and CO2 values. They can directly control an EC fan, an AC fan speed controller or a damper actuator. The black mounting flange simplifies installation on circular ...

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

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 ...

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors ...
