Simple LED Bar Graph CO2 Sensor : 4 Steps (with Pictures ...

This inspired me to build my own variation of a CO2 sensor using the SCD30 sensor that I generously received for free from my employer. The SCD30 is relatively expansive compared to some other gas sensors because it is a non-dispersive infrared (NDIR) sensor. It measures the absorption of specific wavelengths of light characteristic for the gas ...

DIY CO2 auto controller - Kit - UK420

Mar 14, 2017· DIY CO2 auto controller. I've bought an NDIR CO2 sensor from China that has a 0-10,000PPM range which I'm using to make a DIY CO2 controller. This type of sensor uses a beam of infrared light and a sensor, detecting CO2 that disrupts the beam. At the moment the electric CO2 regulator is being replaced by an LED since I haven't bought one yet ...

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

Jun 23, 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 ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
