Today, Wireless Sensor Networks (WSN) are potentially one of the most important technologies of the 21st century. The utilization of wireless sensor based control systems have been augmented to a very great extent due to reduced cost, better power management, ease in maintenance, effortless application in remote and hazardous areas. This paper describes the design and implementation of a Smart Sensor node while supporting secure wireless communication. The architecture also provides approach to update operating and monitoring parameters of the distributed system. This smart sensor platform has been realized on the basis of a low power microcontroller AVR ATmega-16L, an RF transceiver CC2500, Accelerometer and LPG sensors and uses the SPI protocol.
