A radar sensor able to detect children or pets left behind in a vehicle could help save lives.
The sensor developed by a team from the University of Waterloo attaches to the car’s ceiling or rearview mirror, where it emits radar signals that bounce throughout the cabin. The reflected signals are analyzed by an artificial intelligence algorithm to detect the signs of motion caused by breathing, which could indicate a child or animal left unattended. If such signs are identified, the system will sound an alert and prevent the doors from locking.
