Design and Implementation of Smart Irrigation System by using Advanced Level Sensor

Abstract

Agriculture is one of the biggest economic sectors in our country, many farmers and labor depend upon agriculture to develop and to increase the economy of our country. Water is extensively used in modern agriculture. Effective and economic use of water can enhance yield quality and quantity, thus ensuring food security for the ever-growing population around the globe. Excessive use of water to produce crops causes the water level of the ground to go deep down as a result shortage of pure drinking water is a big threat to us. To grow 1kg of paddy requires 2500 liters of water, but farmers of Bangladesh are using 3300 liters of water to produce 1kg of paddy which means 800 liters are just wasted. In India, the numbers are much higher, almost 5500 liters. In this smart irrigation project, we utilized modern sensor and IoT technology to efficiently manage the water in agriculture. The sensor collects 7 important soil parameters and provides the data to microcontroller. Based on sensor data and the crop type microcontroller determines the amount of water required for the crop and controls the water pump accordingly. All the data can be visualized from the LCD display and as well as from the remote dashboard almost in real time. The pump can also be operated manually using smartphone or web browser.
