Microcontroller Based Weather Data Logger

Data logger periodically measures various real-time meteorological parameters and stores for future use. The Microcontroller based automatic weather Data Logger is arranged that it can automatically operate unattended for long periods up to few years. The system has its own automatic power generation from battery backup for maintenance and storage to achieve the uninterrupted operation. The proposed set up consists of four sensors (to monitor and store air temperature, relative humidity, leaf wetness and soil moisture content) interfaced with a 32-bit micro controller. The developed system is tested and the results are discussed.
