General Description


The RE 200B is a passive infrared sensor designed to pick up heat radiation of wave lengths in a band around 10 microns. It contains two active elements con?gured as balanced differential series opposed type. This results in good compensation of environmental temperature and excellent sensitivity for small changes of a spatial temperature pattern. Thermal signals far below one microwatt are suf?cient to trigger a suf?cient output voltage change.
Functional Description
If the active elements of the PIR sensor are exposed to a change in the surrounding temperature ?eld, electrical charges are separated within the sensor elements. The voltage across the sensors controls a J-FET source follower impedance converter and thus modulates the output current of the PIR detector.
The spectral sensitivity of the sensor is controlled by the optical transfer characteristics of the window in the case and has been optimized to pick up radiation of the human body.
Applications


♦ alarm systems

♦ consumer electronics

♦ human body detection

♦ automatic switches
