This bool presents the design and development of Irrigation controller System built around a microcontroller. The system consists of microcontroller, peripherals including RTC, LCD and driver circuit relay to switch on/off a motor. Different parameters i.e. soil moisture, water contents, intensity, humidity, wind speed, temperature etc. The key objective of this paper is to report on a developed indigenous low cost time based microcontroller based irrigation scheduler which performs user defined functions and outputs commands to derive appropriate actuators (solenoid valves, motor).
