Pyroelectric Infrared Sensor
Pyroelectric infrared sensor is a sensor to catch the faint infrared rays generated from the object. This is for the sensing objects, does not exert any impacts. And, it will deliver the information about the presences and situations of the sensing objects. Pyroelectric sensor, to the far infrared rays from near-infrared rays, is a general-purpose sensor with high sensitivity with a wide detection range of wavelengths.
