Along with electronics technical development, the mankinds continuously study and continuously innovate to record, the consciousness of people39。s oneself defends also gradually strengthen. The infrared ray has concealment and design a bunch of infrared ray in the place of openair protection can expediently examine if someone es in and goes out. This kind of device designs of important point: One is effective ability judgment if someone39。s member gets into the room。 The other is the earth increment the protection scope is possibly. The alarm can detect infrared issued by the body, can sound an alarm into the alarm monitoring area, and applies to homes, offices, warehouses laboratories and other important occasions, antitheft alarm. This design is to make use of heat to release electricity infrared ray to spread a feeling machine to probe into the human body infrared ray that the infrared signal principle design that the human body radiates es out to respond to report to the police a machine. The contents of sensor is extensive, vivid applied.
