The World's Smartest Smoke Detector?

By Brian Rhodes, Published Oct 15, 2012, 08:00pm EDT (Info+)

False smoke alarms kill. When 'traditional' smoke alarms are tripped by false sources like steam or weather changed, many people resort to disabling them to prevent annoyance. Thanks to a new type of sensor, a manufacturer claims it is producing a 'smarter' detector that overcomes traditional weaknessess and alarms on more than just smoke. In this note, we examine USI's IoPhic Sensor [link no longer available], investigate the 'difference' in sensor technology, and compare the cost against traditional models.
