ultrasonic parking assistance

I have a project to make Ultrasonic parking assistance? can you help me??

My project like this:

1.This Ultrasonic parking assistance can only detect something at the rear of vehicle.
2.This Ultrasonic parking assistance can’t detect something in right side and left side of the vehicle.
3.This Ultrasonic parking assistance will not show the distance of the object behind the vehicle. But only produce beeps when something behind is so close to the vehicle.
Use :Microcontroller PIC16F88, IC 7805, IC MAX232.
 

pic16f88 beeps

What sensor do you use? I know its ultrasound, but what type? Basically the device only measure the wave propagation and do calculation. the closer the distance the faster the beep frequency.
 


Search with your keywords right in this website, there is a very good project here.
