Zigbee Based Portable Wireless Industrial Sensor Data Monitoring System using Atmega8

In power plants, chemical plants and manufacturing industries environmental conditions play great role in quality of the output. Therefore sensors are placed for monitoring environmental conditions. There are places in industries where human intervention is not possible, in such places sensors are placed and their data can be monitored on display panels at different locations. This system can be made wireless by using XBee-PRO RF Module based on the IEEE 802.15.4/Zigbee standards. Zigbee is a low power wireless transceiver device which in combination with processing unit can be used for sensor data monitoring. A low power microcontroller unit ATmega8 is used to take sensor data, process it and transfer it to Zigbee to transmit at remote location. At remote location a handheld device contains another Zigbee receives data packets and transfers to microcontroller. Microcontroller processes the data packets, calibrate it and display it on LCD (liquid crystal display) for monitoring. In this way, a handheld monitoring unit is created to monitor real time sensor data remotely.
