This document describes a PIR and GSM based home security system. The system uses a sensor to detect intruders and notifies the homeowner through an alarm and SMS message. It continuously monitors the sensor status and automatically sends SMS alerts to the user if the sensor is triggered. The system aims to provide security for homes, banks, and companies through detection and remote notification capabilities.

Everyone wants to be as much secure as possible. The importance of GSM technology is increasing day to day so an access control system using mobile phones indicates a vital security link. Making use of this wireless technology for device accessing or controlling by sending an SMS or by making a call from the control unit with help of Micro controller and GSM modem we can monitor and provide security. OBJECTIVE: The main objective of the project is to provide security for the houses/banks/companies etc., by detecting the intruder and indicating it by producing an alarm and also sending an SMS to the respective owner. GSM modem provides the communication mechanism between the user and the microcontroller based control system by means of SMS messages. METHODOLOGY: By using this system we can secure industry or home very easily. This system consists of a sensor which monitors the area and gives an output whenever a person is moving at the premises. The output of the sensor is given to the control unit, when the control unit gets an input from the sensor then it produces an alarm also sends a command to the GSM modem so that the modem sends an SMS to corresponding number which is preloaded in the control unit. This system continuously monitors the status of sensors connected to it. If any of the sensor gives the output indication, then micro controller based system automatically sends the SMS alerts to the user. After completion of the command implementation this system sends the confirmation messages back to the calling user. skesystems@gmail.com Vijayawada Hyderabad Page 1
