Problems solved by technology

Due to the heating of mechanical and electronic equipment during the driving of the car, the heat in the car environment will change, and when the car is parked, the objects in the car will be exposed to sunlight and the heat in each area of ​​the car will change rapidly. Therefore, the applicable environment of this scheme is limited. low accuracy
[0004] In the prior art, there is also a solution to detect people in the car through seats, but in this solution, each seat needs to be arranged, which is inconvenient for installation and maintenance
