Abstract: Security is the most important in day to day life for almost all the sectors of the world. The development of self security alert system using wireless sensor network is presented in this project The main aim of this project is to secure a person under risk by automatic alert system using Peripheral Interface Controller, mobile communication and Force Sensing Resistor. Force Sensing Resistor at the bottom of the foot senses the force being applied. The analog information from this resistor will be converted into digital for further processing by the Microcontroller series. Whenever a person is in distress, he/she has to hit the sandal forcibly on the ground to activate the control unit. When the applied force exceeds the threshold level, the signal will be transmitted to the Radio Frequency Transceiver through Serial Peripheral interface. When Radio Frequency Transceiver receives the signal, it is given to the Microcontroller. Global Positioning System is the receiver that collects data from the satellite and feeds the exact location in the form of latitude and longitude to the user’s mobile. Communication is possible by sending a text message in the predefined format to the GSM modem. The main concept in this design is introducing the mobile communication into an embedded system for the purpose of security. The design unit is very simple and low cost.
Keywords: Global Positioning System (GPS), Global System for Mobile Communication (GSM), Force Sensing Resistor (FSR), and Peripheral Interface Controller (PIC).
