INNOVATION: Ashtavinayak Patil and Sandeep Karajagi with their device for water management

GULBARGA: A project on effective water management techniques devised by three final year engineering students of Hiresugar Institute of Technology at Nidasoshi in Belgaum district won the first prize in the third National Technovision Exhibition of projects and the second prize in the Shrusti Exhibition of projects at Basaveshwar College of Engineering in Bagalkot recently.

Sandeep Karajage and Ashtavinayak Patil from Malikwad village in Chikkodi taluk of Belgaum district and K. Chintamani of Siruguppi village in Chikkodi taluk have devised the project that not only saves water, but also monitors the availability of water at its source. It also monitors power fluctuations and corrects phases in electricity distribution to motors.

Mr. Sandeep Karajagde and Mr. Ashtavinayak Patil, who were here to participate in the National Technovision Exhibition of engineering projects at the PDA College of Engineering, said their project, "Cellular controlling and status logging system", helped in controlling an irrigation system, right from switching on the motor, measuring the quantity water required for irrigation and measuring the level of water at the source through an electro-mechanical system using cellphones by sending SMS.

The system has three cellphone sets, a personal computer and a micro-controller circuit. One cellphone is fixed to the micro-controller circuit placed near the motor that pumps water. The second one is attached to the computer at the house of the farmer and the third cellphone will be with the farmer. Sensors are placed at various locations in the field and at the water source to check the flow of water and its availability.

When the farmer wants to release water, he need not go to his field. All that he has to do is to send a pre-fixed SMS to the cellphone attached to the micro-controller circuit. After receiving the SMS, the cellphone attached to the micro-controller circuit will switch on the motor and send an SMS on the availability of water, extent of water released into the field and the electricity supply position to the cellphone with the farmer and to the one fixed to the computer.

Once the water is released into the field, the sensors placed in different locations would keep a tab on the levels of the water in the field. Once the water reaches the pre-set levels in the field, the sensors will trip the motor to stop the flow of water. Even if the level at the water source is low, the sensors there will send signals to the micro-controller circuit not to switch on the motor.
