Alarming fridges - alert for midnight snacks

Pippa Rojo on August 29, 2007 | 1157 Views

Escalating electricity bills, along with warming food could be a thing of the past with this 3V battery-powered fridge alarm that beeps if you leave the door open for more than 20 seconds. When the fridge lamp illuminates, the alarm’s photo resistor lowers its resistance, the IC starts counting down and after a preset delay the piezoelectric buzzer beeps for 20 seconds.

Follow this link to find out more about a new energy saving device for fridges.
