If there are no children or pets in the car, the detection of the oxygen concentration will be stopped, and it will not be opened. sunroof. Or the automatic alarm system detects the gas state in the car through the sensor in the car. When an emergency occurs, the car sends out an alarm to remind the pedestrians next to the car and turns on the car exhaust fan. Or when the car is locked, if there is something moving in the car, the car will sound an alarm, which prevents children from being left in the car and causing danger while preventing theft. The existing technology is not humane enough and has little flexibility.
