Design of a Anti-Theft Alarm Monitoring Circuit Based on Mobile Phone

Abstract:

For to steals, robs, and so on accidents to carry on the effective monitor and the warning, a burglar alarm monitoring circuit is designed by using mobile phone, which utilizes a pyroelectric infrared sensor to detect the human body moving signal, when someone moves in a monitoring region, pyroelectric infrared sensor can detect the human body moving signal, and converts it to the voltage signal, the signal is amplified, comparison, time delay, control the relay connect or disconnect the mobile phone to the owners alarm. The components are welded on the circuit board, and connected to internal lead wire of mobile phone key, electrifying testing, it can realized anti-theft alarm and monitoring function.
