You didn't mention any requirements for resolution, accuracy, response time,
object size, interface type, or cost. Without knowing those, you could
easily go with either infrared or ultrasonic for that kind of range. Here are
two ideas:

Both would require a 5V regulator.

Hallo there
Hi, I want to carry a research project on a sensor that can suitable to
Detect an stable object. I would like to get an idea on how i can implement
my project. I want to implement a sensor which can emit a ray or any kind
of non hazadous emision which will respond to an object in a distance of
one meter 1m then send the feedback to a board to produce an oscillating
signal hence the sound to prompt the user about the object he will be about
to hit.
Specs
Distance: Between minimum 1m and 3m maximum.
Voltage:12V Dc
