The Design of Indoor Infrared Alarm
Abstract:
This design uses the pyroelectric infrared detection technology, single-chip microcomputer control. Pyroelectric infrared sensor sensing the infrared thermal radiation (the body temperature is 37 degrees) of the invaders, converting it into a low frequency signal, passing to microcontroller through amplified circuit. Finally, it implements anti-theft through the alarm module.
