To Develop Sensor Networking And Weather Station Monitoring System Without Human Intervention Using Wireless ZigBee Technology. The Project Is Mainly Targeted Towards The Reliability Of The Pollution Monitoring System. A WMS Keeps Track Of Temperature, Humidity, Wind Speed And Direction, Rainfall Amount Etc. The System Displays These Readings In Real Time On A Display. It Also Keeps Track Of Historical Information On An Hourly And Daily Basis. This Data Can Be Display On LCD. Various Techniques Are Used To Monitor The Weather Like Satellites, Radars, Microcontrollers And Many Other Simple Instruments. Weather Can Also Be Monitored By Using Remote Wireless Sensors. Zigbee Is The Latest Wireless Weather Monitoring Technique. The Existing Monitoring Systems Of Weather Monitoring System Are Manual. We Need Human Support For So. There Are Limitations For Human To Know About Exceeding Hazardous Parameters Of Environment. There Are Chances Of Human Errors. Like Human Calculations May Not Be Precise Sometimes. Or Human May Not Cover Larger Area. We Need Some Smart System Which Will Automatically Measures The Parameters. In This Application, Wireless Sensor Network Can Solve The Problem, Where Parameters Calculations And Controlling Will Be Precise Even Over The Larger Area
