Abstract: Development of an automated weather station with remote data transmission capability is presented. The complete system consists of three separate modules for data collection, data storage and data communication. The modules communicate with each other serially and are controlled by three separate PIC18F452 microcontrollers. The data collection module is interfaced to a set of sensors to collect weather parameters such as temperature, humidity, wind speed, wind direction, pressure and rainfall. The data storage module saves the captured data in real-time to a micro SD card. The data transmission module transmits data to a central station through a GSM or GPRS network. The selection of the network takes place automatically before transmitting data. The weather data can be viewed in real-time through a graphical user interface (GUI) located at central station. The modular nature of the design allows user to replace the data transmission module by RF link for transmitting data to locations within 100 meters.
