Abstract:
This project overcomes a serious issue we face in the life. It will help all parents to rescue their
children's lives. When they are trapping inside a car for a long time, beside to saving lives when
car had an accident.
The system receives different signals from sensors that are attached to it, and then processes
inputs by the microcontroller. In simple words, the device measures the oxygen concentration
inside a closed car; if there is someone in it. Which is detected by the motion sensor. Then it
compares the readings of carbon dioxide sensor or temperature and humidity sensor to a
predefined value. If it is low; then the device react to rescue trapped persons.
Beside to, if the system receives a signal from ADXL345 sensor , the car gets an accident .
The system reacts to the situation and sends an emergency message to the civil defense.
The first step is investigating the existence of human beings by the motion sensor, if there is
anyone. The second step; when the oxygen is getting low the device opens the driver window by
a certain limit, and then sends a message to parents on the defined number of mobile. If they
were too late, it sends a message to emergency containing the coordination of the car depending
on GPS readings.
