PIEZOELECTRIC BURGLAR ALARM

Since the late 1970s, there has been talk of home automation. Yet, as technology and services improved, so did people’s expectations, which affected how they perceived home automation systems. In this work, we use a modest PIR built around an Arduino controller to construct an advanced electronic security system. PIR and IR sensors detect an intruder’s presence, and the controller interprets the signal from the sensors. Intruder detection activates the bell, places a call, and sends an SMS to a predetermined number using a GSM modem. In tandem, the controller activates a camera to record an intruder’s image and send it to the person via GSM module AT instructions.A excellent security system is centrally located, making it easy to maintain a close eye on the entire area, which lowers personnel requirements and labour costs.
