Abstract: In an industry, number of electrical equipments are connected at different locations of the plant. It is difficult to monitor all the parameters of every equipment continuously, also collection of such numerous information and analysis is time consuming. The Wireless Industrial Surveillance System using real time operating system (RTOS) is an application designed to monitor the individual device or parameter at the time of requirement. This is a kind of wireless sensor networking used in supervisory control system. It can be designed with a single cluster sensor polled by the central monitoring station for its status and also the control operation of stand by device can be made from the control room.
