Ultrasonic Proximity Sensor help!

[stu_c]

Hi all
I wonder if you guys can help me and point me in the right direction, we are after a 12V ultrasonic sensor that is waterproof to put on the back of a truck, when a solid item gets within the sensors range we want it to trigger a Light/LED preferably from Green - Yellow then red depending on the distance, I have no idea about Electronics and wondering if someone can give us a helping hand to do it.

the control box can be put inside if required

The main things we need are
1: waterproof
2: 12V
3: to be able to adjust the sensor ranges for each colour

I presume I would need something similar to this but again no idea :\


if anyone can help would be ideal, we are based in Milton Keynes UK

Hi Stu,

Most ultrasonic sensors are going to be designed to operate a 5V and work with Arduino or Raspberry Pi. for your use case I'd suggest an Arduino would be better than a Pi (you want to run a very simple program and be able to quickly turn it on and off without any fussing about).

Parts List:
5v UBEC (or other method of supplying arduino with 5V)
Arduino Nano v3
Waterproof ultrasonic sensor
Transistors to switch the 12V Lighting.
wires to connect the components

Arduino program: pretty basic, use the sample arduino program for range finders and operate the three outputs based on distance returned by sensor.

Thank you for the reply as I said I am totally bewildered by electronics so well beyond my knowledge I'm happy to pay someone to do this if possible, we will be having a switch inside the truck cab to turn this on/off but it's just the sensor kit side of things I'm struggling with
