Abstract: The “Air Alternator” is a device that will be designed to protect a child or pet if mistakenly left in their vehicle. A motion sensor will be installed inside of your vehicle. Once the vehicle has been turned off the “Air Alternator” will be able to turn on the air in the vehicle if the outside temperature is hot. If the outside temperature is cold, this device will turn on the heat. Also once the system has been activated it will be designed to sound an alarm on the drivers' keys that can't be shut off until the driver restarts the vehicles engine.
