Now a day, the Wireless Sensor Network (WSN) is a revolutionary field of Electronics and Communication Engineering. WSN is a network of devices, called Sensor Nodes (Motes), which sense the physical status of the area and communicate the information collaboratively through wireless link. According to architecture, it is a network of finite number of sensor motes, wirelessly routed to each other and to the base station. Emphasizing the standards of IEEE 1451 and IEEE 802.15.4 the hardware of the Mote is designed. Present Mote comprises an array of five sensors, which physically interact with the environment. The values of the parameters, in real units, are also displayed on the smart LCD and transmitted towered base station. The smart Graphical User Interface (GUI) is designed on PC which is integrated with coordinator mote. The data stored in real time is made available for processing, presentation and deterministic management. The Wireless Sensor Network is designed successfully deployed for on-line monitoring of the environmental parameters with great reliability and preciseness.
