Abstract

Security system has become one of user needs now days and user are keenly to pay money to buy these devices. Wireless Security system is one of the devices in the market but because the technology that is used the device is very pricey. The objective of the project is to design wireless security system that is more affordable for user. The second objective is to build a wireless and portable security system. The third objective is to design a flexible and easier installation device for user. The wireless security system has three main parts that is the sensor system, the wireless system and the alarm system. The sensor system includes door sensor and motion sensor. Components that will be used for the door sensor is shock and magnetic sensor. While components for the motion sensor is infrared sensor and PIR sensor. Next the RF module 433MHz will be used for the wireless module. Finally the third part in hardware development is the alarm system that is consists of LCD display and a buzzer. Microcontroller 16F877A will controlled the three main parts of the wireless security system. When the sensor system is active, it will send a signal to the alarm system that will then alert the user. The communication range between the sensor system and the alarm system is up to 50 meters.
