Hi,
This is like event data recorder / black box for vehicles. I developed a prototype of this 2 years back, with
1. lane sensors( proximity sensor),
2. impact sensor( pressure sensor),
3. Distance measurement ( Ultrasonic),
4. engine temp sensor ( LM35),
5. GSM,
6. GPS,
7. PWM for DC motor speed control, for reverse, gear 1,2,3,4,
8. CAN bus to get the data of all sensors and
9. store it in EEPROM (AT24c04),
10. jumpers used to show break failure , and wiper failure, and seat belt.....
11. push button for ignition key,
12. RF modules to show that car is controlled through PC...
I used LPC2129 for my project...
