5 People Who Were CAUGHT Leaving Dogs In Hot Cars… INSTANT KARMA 💢

Engineers have developed a compact, inexpensive sensor that alerts when children or pets are left alone in a vehicle.

A danger to the health and life of a child or pet arises in very hot or cold weather. To solve this worldwide problem researchers from the University of Waterloo combine radar technology with artificial intelligence.

The wireless device they created has the shape of a disk with a diameter of 3 cm, is powered by a battery and is designed to be mounted on a car’s rear-view mirror or ceiling.  A built-in sensor sends radar signals that bounce off people, animals and other objects in the car. Next, AI analyzes the received data, identifying and classifying living objects by their breath.

If a child or the pet is accidentally (or deliberately) left in the car, the system prevents the doors from locking and begins to beep, warning the driver, passengers and people around them that there is a problem.

Unlike cameras, this technology maintains privacy and has no blind spots since radio waves can penetrate seats..

Engineers are already exploring the potential of using the device to monitor drivers’ vital signs for signs of fatigue, distraction, disruption, illness or other problems..

In addition, the analysis allows you to determine the number of passengers and their location in the vehicle. This information can be used to calculate the cost of shared transport services or to allocate vehicles to parking lanes..

Recall that recently, scientists have developed a bioacoustic identification technology that allows you to determine a person’s personality by the sound of the body..
