Sensor Piroeléctrico

Overview | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· PIRs are basically made of a pyroelectric sensor (which you can see below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. The sensor in a motion detector is actually split in two halves.

US4800278A - Pyroelectric infrared sensor - Google Patents

External noise in an infrared sensor for a ceiling type human detector is suppressed by increasing the conductivity between a conductive window and the can and improving the temperature compensation by offsetting any difference in the electromotive force per unit area of the inside and/or outside electrode of the sensitive element consisting of coaxial electrodes with different areas.
