The authors' intention is to design a device to find out the presence of human being using radio signal strength variations based on the simple fact that that human body interferes with radio signals by causing shadowing effects. A presence of irregularities in the radio propagation pattern denotes possible presences of human beings. Using IR sensor and RFID tag, they can easily detect the presence of human beings in the military border. ZigBee transceiver used to transmit and receive the information through wireless communication.
