The threats and damages done through criminal activities in our society make it imperative to blend technology to provide sensitive security. This paper designed a micro-controller based SMS alert system for intruder detection. The system is built around a PIC16F876A microcontroller programmed with Global System for Mobile Communication (GSM) to GSM module connected through MAX 232 integrated Circuit (MAX 32IC), to the microcontroller. The design takes information of intrusion from proximity sensor and vibration sensor. The system was programmed with the user’s mobile number for a customized SMS notification of intrusion for each of the sensor. The response time between intrusion and SMS alert was tested to be 20 seconds under normal available network.
