Weather Monitoring System Using Wi-Fi

This paper presents a weather monitoring system for monitoring parameters such as temperature, pressure, humidity, rainfall, wind speed and direction. All the necessary parameters to be monitored are sensed using various sensors. For temperature pressure and humidity measurement readily available sensors have been used whereas wind-speed, wind-direction and rainfall have been measured using rotary encoder, opto-coupler, tipping bucket technique respectively. The measured data is processed using micro-controller based system and made available wireless on the server for storage and access continuously. The system is totally automatic thus minimizing human error. This kind of monitoring system can be used in industries, agriculture, meteorological department etc for data acquisition and analysis.
