Cellphone-packing smoke detector dials for danger
Recently I wrote about GSM doorbell which may call to your mobile phone when somebody stays behind your door and wants to meet you. Here is a smoke detector with GSM module produced by Japanese company Keisoku Giken. 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.
