Abstract: “Safety is the most important concern in all the sectors. We can able to provide special security in WPAN and it is made possible by integrating various sensors with ZigBee network. It to provide simple and effective security solution for whatever the threatening come. The intimidating may be a human intrusion, metal detection, fire hazardous problems and many more problems. This paper develop the real time prototype which is an integrated system designed for heat detection using infrared based heat detection sensor and alkali metal detector in a large nuclear reactors using CC2500 ZigBee Transceiver module. Anybody intrudes in that particular area can be Fire detector detected, its work up to 10m distances. Fire Sensors: True model fire sensors will be employed in this project, which can capture the fire and provides logic signals to the electronic circuits. Metal detector: An inductive proximity sensor will be used in this project to detect bomb and metal hazards. This sensor is so in”
