Mangaluru, Dec 13, 2016:  Three innovative projects designed by students of various schools in Dakshina Kannada district have been selected for the 43rd Jawaharlal Nehru National Science, Mathematics and Environment Exhibition at Bengaluru from today, December 13. These projects include a sleep detector, Petrohol fuel from fruit waste and an emergency mobile charger.

The sleep detector is designed by Thejas, a student of Holy Family High School, Bajpe. The aim was to develop a system to detect drowsiness. He said: "I use public transport to go to school every day and observed that many parents dropped their children on two-wheelers. The children usually ride pillion and often, the small kids aged 3 to 8 years, start dozing. There are chances of them losing their balance and falling down. So I thought of a device to identify the drowsiness of a child which can alert the parent. When I discussed this with our teacher Vasudeva Rao, he suggested that this equipment can be used by drivers to detect drowsiness during night travel."   The low-cost sleep detector can be prepared by using an infrared-based eyeblink sensor, buzzer, 4.5 volt battery, battery holder, switch, wires and spectacles.

Sharanya, a student of Carmel High School, Modankaup, Bantwal, designed an emergency mobile charger. Due to prolonged use of a mobile for chatting, downloading files, etc. the battery drains very quickly. The emergency mobile charger is a solution, she said. It uses a battery or solar cell, an integrated chip, resistor, LED bulb, a printed circuit board, 9V battery, solar panel, supply wire of charger, DC motor and fan.

A science working model Petrohol Fuel from fruit waste by Olvita Sheeba D’Souza and Minolin Eena Pinto, class 10 students of Sacred Hearts’ High School, Kulshekar has been selected for a presentation in the Idea Exchange Session - Among Young Minds, a separate session at JNNSMEE.
