Agriculture in Ethiopia is one of the main sources of living and it has also a tremendous impact in the economy for majority of the peoples. Due to the lack of rains and scarcity of land reservoir water in the field of agriculture, use of proper method of irrigation is very much important. Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes waste. For this purpose; this automatic plant irrigation system is used. Since the farmers working in the farm lands are only dependent on the rains and bore wells for irrigation of the land. It also improves the traditional irrigation system in Ethiopia enabling to have high efficiency and low water usage of the existing irrigation system being tedious, time consuming and very wasteful in water usage. The system derives power from solar energy through photo-voltaic cells to operate the Self-controlled tanker filling and water feeding irrigation system with a microcontroller-based photovoltaic maximum power point tracking control system. Hence, dependency on erratic commercial power is not required. The main objective of the project is to develop an irrigation plan based on Indigenous, low cost, time-based microcontroller-based irrigation scheduler. The study, therefore, focuses on improving agricultural, soil conservation and harvesting periods, water utilization and water management. To achieve this, it needs to measure the different temperatures, the amount of water and soil moisture it has. This system provides design and development of irrigation control systems using the PIC16f877A type control unit. The system includes controller, LDR, temperature meter, water sensor, LCD, and circuit relay to turn (on/off) a motor and different control valves. Generally, the system has three independent regulators: the sun's energy to the electrical system, the flow of water, and tanker filling and water feeding system. Here it uses the highest power point monitoring system to improve the effectiveness of the solar panels and to utilize the power of the pulses. Then, with the help of the pump, water is conveyed under pressure through a pipe system to the tanker or to the field where it drips or sprinkled onto the soil through sprinklers or drippers. Tanker filling system is controlled automatically from the feedback of the sensors installed in the tanker and water feeding to the field will be controlled with a similar way using humidity level sensor located in the soil of the field.
