GUWAHATI: Nicky Tahbildar, a school boy from Assam, has drawn attention by making a science model aimed at enhancing agricultural productivity by providing timely water supply just by dialing a cellphone.
Nicky has been selected for a state-level competition of the ‘Inspire’ award scheme under the department of science and technology, from Sonitpur district recently. "Very often we see that farmers have to walk miles to reach their fields for turning on water pumps. They have to wait as long as the pumps run. It is a wastage of time and energy. Moreover, a farmer does not get electricity round the clock. By using this device, a farmer can operate the water pump by staying at home or anywhere else just by dialing his cell phone to another phone," said Nicky, a Class X student of Assam Valley School.
He said the device contains a DTMF circuit and a relay circuit (which triggers the water pump) connected with a phone (with auto response mode). "
The motor is controlled by making a call to the mobile connected to the device.
