Forgot to turn AC off? Don't fret, send SMS

Ahmedabad: Remember the ad that got an anxious Shekhar Suman in some foreign land worrying about the fan he left switched on back home in India and the fat bill he'll have to pay for it? Well, had Suman met three teenagers of Nirma University (NU) students then, he would have spent Re 1 on switching it off—by SMS. Three students of NU have come up with a system worth Rs 1,500 which can control anything from a washing machine to traffic lights, all thanks to the humble SMS. While the prototype that the students will make in the next few months will have a city-based application, they propose to develop it further to cover a larger area with NU willing to offer Rs 20 lakh seed capital to help them incubate their innovation. Of 150 entries, this SMSbased control system designed by Punit Soni, Sunny Vaghela and Komal Shah bagged first prize at the university's national-level technical symposium held last month, which was judged by scientists from ISRO and PRL. While it's based on the not-so-new principle used in sending SMSes from mobile phones, this innovation widens the applications of the principle and is easy on the pocket. Among its applications, is one where traffic lights can be controlled through SMS, say the young innovators. "Traffic lights operate on timers, which often need manual adjustments. Using SMS, officials can control timers from any part of the city,'' says Vaghela. It can also be used in universities and hospitals. "A doctor sitting in his cabin can check the heartbeat of his patient by sending an SMS to a CCTV in the patient's ward. Connected to the SMS-based control system, the CCTV records the heartbeat and intimates the doctor,'' Soni says. The system is based on interface between a computer and a mobile phone. All you need is two GSM-based mobile phones, one personal computer and the controllable device, such as a fan, bulb, air-conditioner. Interface is made possible using commands given by the computer to the mobile connected to it. "One mobile phone is attached to the PC-based circuit, which is connected to the controllable device. The other, which is in your hand, is used to send the message to this circuit. The software reads the message and sends the command to the device,'' adds 19-yearold Soni. "The entire apparatus, including the mobile, will not cost more than Rs 1,500. There will be no monthly bills if you go for the currently popular lifetime incoming free scheme,'' says Vaghela, also 19. With the university having its own incubator for technical innovations, vice-chancellor N V Vasani assures full support. "We are ready to provide the students a seed capital of Rs 20 lakh, mentoring, industry linkages etc.''
