The key in agriculture is the irrigation procedure. It is important in achieving good yields and it also helps in maintaining good performance of plant. An automated irrigation system is necessary for optimizing water usage for agriculture crops. For long term plant growth irrigation management is necessary. Irrigation is very difficult in areas where there is less rainfall or in dry areas. In this system the soil parameters like moisture, temperature are acquired by using sensors. The environmental humidity and temperature are also acquired by using sensors. The information from the sensors is given to an Arduino board. These values are transmitted to the main controller which is placed in the control section. The information is given to PLC and program is written in PLC in such a way that depending on the values the water level is optimized and supplied to the plant. The system is accessed through the HMI i.e. Human Machine interface which reduces human intervention. Wireless Sensor communication is used to communicate between sensor board and the main controller board.
