Intelligent Energy Saving Using Wireless Sensor Network

This paper intended to provide Intelligent Energy Saving System which can be used for reducing energy consumption and it is used in places like where lighting is important. The libraries will be well illuminated with many lamps and it is also used in industry for temp control and also for humidity control .The LDR senor is used in dark or light sensor circuits.. The LDR sensor have very high resistance but when it is illuminated with light the resistance drops and microcontroller switch on the bulb in node section the command send by server section.The temperature sensor have temperature in calculate degree celcius, if normal temperature goes above threshold value then fault occur which is given to microcontroller and microcontroller send command to switch on fan and cool down the system. The existing system have lots of energy consumption because of manual control over the system and data does not store. the waste of time and energy in existing system then we use proposed system for monitoring sensor data which is transfer by node section. The sensor data transfer to server through zigbee and the collected data posted in web server using GPRS
