Due to the need for movement in the location of the device, the current active child safety devices require the child to be present over a sensor that is placed beneath the child and a car safety seat. As such, it has been found that the current technology experiences false positives due to the requirement of movement in the child car seat.
Researchers at The University of Alabama have developed a vehicle occupant detection and warning device that is retrofit technology to save children and pets that become unattended in vehicles by measuring the carbon dioxide levels within the vehicle based on typical expected exhaling quantities for children and small animals. The device simply plugs into existing DC power supplies in the vehicle and utilizes temperature sensors in order the presence of human life. In addition, and in order to detect whether the vehicle is parked, accelerometers and power detection sensors will detect whether the vehicle is parked. Once a parked vehicle is detected, a warning is sent when carbon dioxide levels and temperature reach a certain level.
- Protects children and pets using passive technology- reduces false positives.
- Does not rely on active sensors in car seats.
- Can be retrofit or installed in new vehicles.
- No vehicle safety devices for pets currently exist.
