Basic Principle of NDIR Gas Detection Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...

DIY CO2 auto controller Kit UK420

20170314· I''ve bought an NDIR CO2 sensor from China that has a 010,000PPM 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, but when the ambient level of CO2 is less than MIN and MAX, the …

NonDispersive Infrared, NDIR, Carbon Dioxide Sensors ...

NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs.
