IR (Infrared) Obstacle Detection Sensor Circuit

· Passive infrared sensors do not use any infrared source and detects energy emitted by obstacles in the field of view. They are of two types: quantum and thermal. Thermal infrared sensors use infrared energy as the source of heat and are independent of wavelength. Thermocouples, pyroelectric detectors and bolometers are the common types of thermal infrared detectors. Quantum type infrared ...

Low Cost IR CO2 Sensors -

However the CU-1107 records the lowest CO2 level over 7 days (can be set from 1-30 days) and uses this as a baseline to recalibrate the sensor to 400ppm fresh air. If the sensor will not be exposed to fresh air auto calibration can be disabled and manual calibration can be used. Click here to learn more about the CU-0017 CO2 …

IR vs TC: Settling the CO2 sensor debate once and for all ...

· IR Sensors. IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter. Higher CO2 levels would cause fewer IR rays to pass through the filter and be detected by the sensor. Low CO2 levels would cause more IR …
