The Hindu Business Line | KV Kurmanath | 23 July 2015 | Hyderabad  |

What started as a routine workshop project might offer a solution to one of the most nagging problems for housewives – placing an order for a cylinder well before it runs out of gas. A three-member team from an engineering college have built an IoT (Internet of Things) product, named LPG Doctor, that can measure the cooking gas level and accordingly send an alert to you as well as your gas distributor, thus placing an order. It can also send alerts on your mobile on gas leakages, if any. The prototype emerged as the seventh-best in a recent start-up workshop at JNTU (Jawaharlal Nehru Technological University).


“We used a GSM network to connect the device with the user and distributor. We devised a software that facilitates communication between the user and the device. There is no storage of data involved,” Chintam Tarun, a student of Vasavi College of Engineering, told BusinessLine. The device has two sensors – one to weigh the cylinder and the other to sniff at gas leakages, if any. Chintam Tarun is planning to pitch for investments at the upcoming second edition of India Gadget Expo to take the product to the market. Tarun has teamed up with college mates Goutham Mogili and Sarath Chandra to form a team at the four-day workshop. The workshop sought to help engineering students get a feel of building start-ups, and the aspects involved. Tarun said the product would cost ₹800-1,200 a piece. “The product looks promising, as it attempts to solve a common problem. Its impact would be widespread if gas firms themselves embrace products like these,” Ramesh Loganathan, President of Hyderabad Software Exporters’ Association, said.- Courtesy

Trust this ‘Doctor’ – The Hindu – N. Ravi Kumar

LPG Doctor, developed by a team of engineering students, addresses problems associated with use of cooking gas cylinder

A forum to showcase skills besides encouragement from people around, matters the most when it comes to bringing out the best in youngsters with an innovative spirit. Nowhere was this evident in recent weeks than at the JNTU-Excite workshop on product engineering and entrepreneurship. Among the products and solutions for which the event served as a platform, one that left a lasting impression was ‘LPG Doctor’ developed by a team of three engineering students. A handy device equipped with sensors and LED display, it may well be a panacea for some of the burning issues associated with cooking gas cylinder use. There are three parts to it, explains Chintam Tarun, a member of the team and a third-year B.E. Computer Science student.

The first task is to display the weight, thus helping the customer ensure against taking delivery of an underweight refill. Domestic use cylinders ought to have 14.2 kg of LPG. The tare weight is printed on the cylinder’s surface. Booking a refill is another feature. “Once the weight of the cylinder in use goes below a set limit, the sensor sends an SMS for supply of a fresh refill. A GSM SIM module provided in the device facilitates this.” The most important aspect of the device, however, is the text message alerts it sends out in the event of a leak. “The device sends SMS alert to two mobile numbers of the consumer,” Mr. Tarun says, pointing out that leak detection systems available in the market only sound alarm. Apart from Mr. Tarun, others in the team are third-year students from Vasavi College of Engineering, Ibrahimbagh, Gouthami Mogili (Computer Science) and Sarath Chandra (EEE).- Courtesy
