A Design of Application Based Wireless Sensor Node

Proposed wireless sensor node is a highly flexible and programmable system on chip (PSoC) architecture along with integrated RF radio chip, which can be adapted to any IEEE 802.15.4 standard based protocol, working at the band of 2.4GHz. This can be accompanied by the RF antenna matched with the interface circuit for various kinds of sensors and peripherals to form a wireless sensor node. This can be very well used to form a wireless sensor network in different domains. This proposed methodology can be used for specific application for improving the WSN stability and performance. This article will mainly present the design of wireless sensor nodes based on PSoC and CyFi radio chip, including the application specific antenna and hardware design for the system on chip for the sensor node and the simple introduction of the application domain. The proposed nodes are used with a special antenna and application based protocol for communication. This design has a better power handling and performing capacity. Further, we have implemented this for the wireless sensor node as well. Keywords—PSoC, CyFi, wireless sensor network; cost effective wireless sensor nodes;
