A new device, developed by a team of researchers at the University of Waterloo, combines radar technology with artificial intelligence (AI) to detect unattended children or animals with 100-per-cent accuracy.
This small, inexpensive sensor could help save lives by triggering an alarm when children or pets are left alone in vehicles.

Small enough to fit in the palm of a hand at just three centimeters in diameter, the device is designed to be attached to a vehicle’s rear-view mirror or mounted on the ceiling. It sends out radar signals that are reflected back by people, animals and objects in the vehicle. Built-in AI then analyzes the reflected signals.
