Abstract
Automation facilitates the world for us. In this paper we have done it for making easy for farmers. Nowadays irrigation process has been converted as a complex process. Because of less manpower is available for low paid jobs like these. Not only man power but also time and over exploitation of energy made this problem as a bulk one for former. So automation of irrigation system is needed to overtake these problems. In our project we have done the total irrigation system as a non human interface system by using PLC (Programmable Logic Device). PLC contains lot of relay switches which are turned on or off by some logic. So we can use the PLC as an intelligent system which controls all devices. In this process all fields are irrigated one by one. Water level sensors are used to detect the required water level in the field and send the signals to the PLC. PLC closes the corresponding field’s solenoid valve and opens the next field’s valve. PLC saves the water during rain time by the way of switching off the motor. It saves the motor during drought period (i.e. if the water level decreases in the well). The irrigation process can be automated continuously for an over a period of time by using timers in the PLC. This type of automation is high sensitive compare to other because of intelligent PLC.
Highlights
Irrigation is the inevitable process for all crop fields
The conventional method of irrigation causes the over exploitation of water, electricity. It leads to the high investment and care about the irrigation process because of less man power whose are needed for these kind of jobs [12,13,14]
Water flow control is the main part of the irrigation process which needs man power in the conventional method
Summary
Irrigation is the inevitable process for all crop fields. Still there is no sufficient method for irrigation process. Since we concerned the paddy fields where should be maintained the water level and the timing irrigation process [9, 10] This system can be integrated for all type of agricultural lands in future because of the artificial intelligence of the system. The conventional method of irrigation causes the over exploitation of water, electricity It leads to the high investment and care about the irrigation process because of less man power whose are needed for these kind of jobs [12,13,14]. It may create inevitable defects in the motor which cannot be stopped at right point of time. Shanmuganantham: Agriculture Monitoring and Smart Irrigation System Based on Wireless Sensors
