Project Description:

India is the largest freshwater user in the world, and our country’s total water use is greater than any other continent. The agricultural sector is the biggest user of water, followed by the domestic sector and the industrial sector. Groundwater contributes to around 65% of the country’s total water demand. Today water has become one of the most precious resources on the Earth. And one of the most important factors in agriculture is water availability.
Irrigation is heart of agriculture; Irrigation is one of the areas in agriculture domain where Information, Communication and Dissemination Technologies (ICDTs) can be employed to open up new exciting directions for research and business. Drip irrigation is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either on to the soil surface or directly onto the root zone through a network of valves, pipes. The Internet of Things (IoT) paradigm aims to bring intelligent interconnection of objects in the physical world through information gathering and dissemination devices such as sensors connected to internet using network protocol and information systems.
IoT technology has diverse applications for connecting devices and making smart decision that have societal applications. Implementing drip irrigation through IoT technology has a wide potential to improve the way farms are currently irrigated. Making use of open hardware system for implementing smart drip irrigation enables changes in the system easily if needed. Generally most of the irrigation systems are manually operated one. These traditional techniques are being is replaced with semi-automated and automated techniques suggested an automated concept of irrigation to use the water efficiently and effectively Drip Irrigation system is implemented based

Thought Process:

Arduino Uno is the heart of the system. It requires 5 volts power supply from the USB connection or other regulated power source. Soil moisture sensor is connected to Arduino Uno. Soil moisture sensor gives a resistance variation at the output. That single is applied to the comparator and signal conditioning circuit. The signal conditioning circuit has potentiometer to decide the moisture level above which the output of comparator goes high. That digital signal is given to the Arduino Uno board. If the soil moisture value is above the Threshold level then the motor will be OFF, whereas if the moisture level is low motor will be ON through the relay.
