Implement an Emergency Rescue Device for Vehicles

The purpose of this study is to design a device that can handle emergency situations when the vehicle is overturned, abnormal gas is generated, or it is accidentally flooded by water. The device is fixed in the corner of the front passenger seat, uses the vehicle power supply as the device power, and uses Bluetooth to connect to the mobile phone. Once one of the above three situations occurs, the device will open the window glass and urgently call for rescue operations. The sensor is divided into two stages to prevent errors in detecting the water level or abnormal gas concentration. The first alarm is a basic judgment that enables the personnel in the car to react to the situation. Once the second alarm occurs, the system will determine that the signal has reached the warning value, the personnel in the vehicle are in danger and the window glass should be opened immediately. This design ensures the safety of the people in the car in the event of a dangerous or unexpected situation, and also prevents unnecessary damage to the car.
