The pyroelectric detector of a flame sensor detects the typical spectral radiation of burning, organic substances such as wood, natural gas, gasoline and various plastics. To distinguish a flame from the sun or other intense light source such as light emissions from arc welding, and thus exclude a false alarm, the following independent criteria are considered:

Pyroelectric infrared sensors detect infrared rays using the pyroelectric effect of pyroelectric ceramics, a kind of piezoelectric ceramics. ※Body temperature cannot be measured with this product.

Pyroelectric Infrared Sensor detects the infrared radiation by using the temperaturedependent feature. It suppresses the interference caused by temperature change, adopts the method of dual sensing elements complementary which improves the stability of the sensor.

Infrared pyroelectric sensor can detect the movement of the human or animal body issued by the infrared and output switch signal, which can be applied to projects that need to detect the movement of human body. Traditional pyroelectric infrared sensors need to be used to realize the thermal release infrared probe, the special chip and the ...

The Pyroelectric Infrared sensor is made of a crystalline material that responds to the change of incident thermal radiation and develops a related electrical signal when a heat source (human body) crosses over the sensor FOV. This type of sensor responds to the variation of infrared radiation rather than the infrared radiation itself. PIR Sensors
