Wireless sensor networks have been very popular research field for the last couple of years. ZigBee is a new technology now being deployed for wireless sensor networks. It is a low data rate wireless network standard defined by the ZigBee Alliance and based on the IEEE 802.15.4. This paper presents the implementation of a wireless sensor network (point to point) to communicate through different Zigbee modules. The different physical parameters such as temperature, light, pH etc. will then be measured through the sensors and the measured values will then be displayed on the LCD.
