14 Jan 2009 13:48 car park system

Hello guys,

I am working on developing car parking system.

In that, I need to draw the graph of the space(occupied & available).
So, in the fig, I need to attach Ultrasonic Sensor to car 3 which has to be parked in between car 1 & car 2.

The sensor coupled with the ckt, will produce the graph of the space available & space occupied while car moves in the direction specified & let the driver know how much space available & guide him how to park.

Please help me in selecting the Ultrasonic sensor for this. Any other guidance you want to give....please dont hesitate.

Piezo electric speakers are often used for generating ultrasonic frequencies. They are very thin, but normally require a small housing to increase performance.
