Student innovates device to control homes via phones

By Rosemary Mirondo @mwaikama

Dar es Salaam. A Tanzanian youth has innovated a device that will enable individuals to control their homes via their own mobile phones.

The device known as Smart House can also switch on and off lights as well as sense smoke or motion even when not at home.

The Vocational Education and Training Authority (Veta) Electronics Level III student, Mr Robert Assey, showcased his device yesterday at the Dar es Salaam International Trade Fair (DITF) .

He said Tanzanians have been facing a couple of challenges in terms of security when not at home and that pushed him to come with an innovation that will solve the problem. “At first, I came up with an idea that did not work out and therefore had to improve it before it could work,” he said.

He explained that his first idea was known as Dual Tone Multi-Frequency that required individuals to have two phones; one connected to the house system and the other used as a handset that could be used to switch off and on the lights even when on away from home to avoid burglary. However, he noted that the device failed because it could not send any feedback and only worked on high frequency phones.

In view of the same, he said that, he tried another option that included use of electronics like GSM model and micro-control and programming devices where he programmed on a computer using a phone discard.

“I also added some sensors, which alerts the owner via their mobile phones.”
