Home Burglar Alarm System Based on GSM SMS Module
Abstract: This paper aims at designing an anti-theft and alarming system under the coverage of current GSM network signal. This system uses MCU as its main controlling chip, it collects heat source signal in specified location using body sensor module HC-SR501 and learns the placement of these heat source spots timely by using the text messages sent from GSM SMS module. This system meets the demand of wireless defense and long-range control. Compared with traditional alarming system, it possesses accurate induction, high stability and low cost.
