1. A warning apparatus, comprising:
- a sensor;
a transmitter system which transmits at least one signal electrically connected to the sensor; and
an indicator circuit, comprising;
an alarm system that provides an alarm signal;
a first receiver, which is tuned to a first signal of the at least one signal from the transmitter system, wherein the first receiver is able to receive the first signal from the transmitter system up to a first effective range;
a logic device which receives input from the first receiver and provides output to the alarm system, wherein the logic device signals the alarm system to generate an alarm, only when the first receiver receives the first signal from the transmitter system and the indicator circuit is closer to the transmitter system than a first distance and further from the transmitter system than a second distance.

Abstract
The invention provides a garage door opener alarm for a vehicle that is only triggered when the garage door is open and the vehicle is closer to the garage than a first distance, but further from the garage than a second distance. The invention uses a transmitter system connected to a sensor, where the transmitter system works in conjunction with a first receiver with a first effective range and a second receiver with a second effective range, which senses whether or not the garage door is open. The first receiver and second receiver are mounted in the vehicle. An alarm is sounded only if one receiver receives a signal while the other receiver does not receive a signal.
