I need someone to design me a device or show me a part that I can buy to measure distance. The device should be able to measure distance to a wall or large object from 30cm (1 foot) to 300cm(10 feet) away.
The device should send a signal between 0-12v that is proportional to the distance measured.
If you design the device, you must provide me all the schematics, part numbers, and detailed instructions on how to make the device.
Thank You.
