A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved.
For example, the PIR sensor monitors change in the infrared radiation of an object. This means that if the object is stationary, PIR sensors cannot detect the motionless object. Environmental factors also should be considered. If the sensor is intended for an outdoor application; snow, dirt and other outdoor conditions can degrade the perfor- mance of the PIR sensor. Heat is a well-known ...
