The design of a programmable logic controller based system to control an automatic irrigation system. The system comprises of three modules: the programmable logic circuits, sensor system and the SCADA monitoring. The irrigation system composes of three samples, simulating three different agriculture fields. The humidity of each field is different from that of other fields according to the requirement of different plantation. It is controlled by two sensors for minimum and maximum humidity respectively. Each sample is irrigated by a separate valve. The valves are controlled by the PLC. If the maximum humidity is reached, the PLC turns off the concerned valve based on value fed by the concerned sample. When all samples have reached their respective maximum humidity, the PLC turns off the main pump. This project is proposed to overcome difficulties faced by the farmers in gaining more profit by increasing the productivity and reducing the consumption of water and electricity. Farmers will be able to monitor and control the irrigation system from one place with the help of SCADA (supervisory control and data acquisition) which does the controlling action through PLC (Programmable Logic Controller).
