Abstract
The present invention, in one form, is an alarm system for detecting the presence of a person locked in a parked automobile. The alarm system includes a motion detector and a temperature detecting element coupled to a NOR gate. The motion detector transmits a low signal to the NOR gate once it detects motion within the interior of the automobile. The temperature detecting element transmits a low signal to the NOR gate if the temperature in the automobile exceeds a pre-determined extreme temperature. The NOR gate, upon receiving low signals from both the temperature detecting element and the motion detector, transmits an alarm signal.
