Designing wireless sensor network with low cost and low power

Sensor network is receiving considerable attention as one of the key technologies to keep track of the parameters in the industrial field. Wireless sensor networks (WSN) integrate sensor technology, embedded technology, distributed information processing and network communication. The nodes of WSN serve the functions of perceiving and routing. Power consumption is the key factor affecting the longevity of nodes in practice. In this paper, we propose a new WSN node using MSP430 and nRF24L01. This operates in license free 2.4 GHz ISM band.. The node senses the event for small amount of time 7 goes to sleep mode for long interval of time. This methods and ultra low power hardware reduces the WSN power consumption. A low power wireless sensor network node is designed and tested. Result shows that this method is adaptive, feasible prior to the other methods.
