The Idea: An inside car alarm.

Deep Dive: This device would need to have a temperature and sound detector to monitor temperature levels and determine if an animal or baby was left in the car. You would also have to build a motion detector to determine the car is parked.

Once the device detects the car is stopped and someone is left in the car, it should call, text and alert the car owner. If the situation continues to get worse, the device should either tap into the automatic windows to roll them down or call the police.

Validation: More than 36 kids die in a locked car per year.

Monetization: You could charge a device fee as well as a monthly monitoring fee.
