A real time sensor data monitoring system for wireless sensor network

In real world various activity monitoring applications have been implemented using Wireless Sensor Network. WSN provides a platform to utilize information from connected sensors. Sometimes a monitoring application requires actual time data storage and analysis for data received from the sensors. A real time monitoring application is required to sense and transmit data to main data center. Main data center has to perform analysis and give response for received data in real time. This paper demonstrates a generic real time Wireless Sensor Network based on ZigBee network to monitor various sensor output. Proposed system uses an open source FreeRTOS as an operating system for sensor node to monitor sensor data in actual time, also a graphical user interface has been provided to represent the received sensor data.
