Abstract - For weather monitoring system and irrigation controller we need to measure different parameters i.e. Atmospheric temperature Humidity Wind speed Wind direction Radiation Soil temperature Sunshine and Rain fall etc. The key objective of this project is to report on a developed indigenous low cost time based microcontroller based irrigation scheduler who performs user defined functions and outputs commands to derive appropriate actuators relay solenoid valves motor. A soil moisture sensor was modeled simulated and tested for achieving with low-cost accurate and reliable measurements. A low-cost high-performance and small temperature sensor is used with the same PCB circuit it can measure humidity also. The tipping bucket rain gauge is used to measure rain fall. After a pre-set amount of precipitation falls the lever tips dumping the collected water and sending an electrical signal. An anemometer is a device used for measuring wind speed and is a common weather station instrument. Hence current research focuses on precision agriculture soil conservation and crop irrigation scheduling and water quantity control for increasing water use efficiency. There is a need to develop new indigenous irrigation controller to improve farm productivity and input use efficiency of water and other nutrients. This system presents the design and development of Irrigation controller System built around PIC16F877A microcontroller. The system consists of microcontroller peripherals including RTC LCD and driver circuit relay to switch onoff a motor.
