The system is composed of ARM Cortex-M3 STM32 Micro-controller, a A6 GPRS Pro Serial GPRS GSM Module, a ATK1218-BD GPS Beidou dual positioning module, an HC-SR501 PIR infrared sensor module, an ultrasonic distance detection module and an OLED display module. The system will constantly detect the signal on infrared sensor. When the sensor detects a person near to the vehicle identified, then microcontroller issue the control signals to track the position of a vehicle by using GPS and send the data to the number saved in system through GSM module. The distance between the obstacle and vehicle will be also sent to the owner's phone.
