pyroelectric infrared pir motion sensor

Pyroelectric Infrared Sensor PIR - Philadelphia University

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 Motion Sensor - Adafruit Industries

25/01/2020· PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of thesensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they arecommonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "PassiveInfrared", "Pyroelectric", or "IR motion" sensors.

Understanding Active & Passive Infrared Sensors (PIR) and ...

11/09/2018· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies authorities, or maybe turns on a floodlight. IR …
