In Japan, Mobile technology is finding its way into all manner of everyday objects such as vending machines, snowploughs, wristwatches and even your favourite pet’s food dish. As of yesterday you can add Smoke Alarm to that list.

The Smoke alarm in question has been developed by Japanese company Keisoku Giken and adds a mobile cradle to your traditional smoke alarm to provide a mobile emergency alert system. When the detector senses smoke, it not only makes a sound but also dials a pre-registered number to alert the owner of the fire.

According to the company, the system could be used in temples and buildings of historic interest, unmanned warehouses, buildings under construction, restaurants and holiday homes. They also predict demand from families of elderly people living on their own. The alarm is now on sale in Japan for 16,800 yen ($140) but to use it you must purchase a separate handset and subscription.
