Carbon dioxide gas moves in and out of the sensor tube by diffusion through the twenty vent holes in the sensor tube. The sensor uses a small incandescent light bulb to generate infrared radiation (IR). The IR source is located at one end of the sensor’s shaft. At the other end of the shaft is an infrared sensor that measures how much radiation gets through the sample without being absorbed ...

Passive Infra Red sensors can detect movement of objects that radiate IR light (like human bodies). Therefore, using these sensors to detect human movement or occupancy in security systems is very common. Initial setup and calibration of these sensors takes about 10 to 60 seconds. The HCSR501’s infrared imaging sensor is an efficient, inexpensive and adjustable module for detecting motion ...
CRIR M1. Inquire. The CRIR Commercial Carbon Dioxide (CO2) sensor is a single channel, nondispersive infrared (NDIR) sensor. Within the CRIR is a sensing chamber with an infrared source at one end and a detector fitted with an optical filter at the other end. The source emits radiation at wavelengths which include the absorption band of CO2.
