Hello!
For a personal project, I want to add a distance measurement to my old car, to have an alert if the front or rear cars are to close to me.
I am looking after a medium to long range sensor (30m to 60m) to measure the distance. Laser distance meter are looking good, but I do not need all the packaging around. Do you have any idea?
Thanks a lot!
For up to 50m.
You do. Weather.
Ut contains the optics (lense) and separates the transmitter from the receiver.
A TOF sensor sounds like a poor choice for the front of a car.
A mm radar sensor seems more dirt-proof.
Leo..
They are close range sensors (up to 15m), and the beam is not really discriminating any object shape, you need many of them with a little bit of coding to understand where the object really is.
I should have better explained, I do not neet the buttons and nice display, agree with the rest!
I would love mm radar, but I do not find any in a "cheap" version!
It looks great, and even below my price range. I will give a try!
You can buy them without buttons, casing and display. With double price.. 
I would think anything optical would be totally useless when it it is exposed to dirt and water.
