Need advise on distance sensor with indicator within 1000mm range

Hi,I'm a total newbie on Arduino and also electronic stuff, but I am however a windows application programmer.

Recently I had discovered Arduino and was doing some reading and figured I should give it a try on my own personal project which involves Sensor and Indicator.

I'm trying to build a button panel, which has no buttons at all but only sensors and digital display.
You may refer to my ugly sketch below.

  • I'm not sure what kind of sensor is needed to get the range i need, which is MIN: 25mm, MAX: 1000mm.
  • I'm worried about the sensor may be disrupted by the side of a wall if I attached it to the corner of a room.
  • I read that using IR would post a problem with natural sun light when they shine on it. True?
  • The indicator is to allow me to show status of the sensor if it's active or inactive and also other labels via different given input.
  • The given input power I have is 24v DC.

Finally, Can anyone point me the right direction to a starter kit that can allow me to complete this project OR perhaps even help me to build one and I pay for it so that I can have fun with it?

Your replies will be much appreciated.
Many thanks in advance.

Hello - Welcome to Arduino.
Ultrasonic sensor will help in this case (HC-SR04 Ultrasonic sensor)

Learn more about Ultrasonic sensor Wikipedia page

You need to see the steps in this amazing TUTORAIL on instructable, on how to achieve distance from it.

also a quick search on YouTube on "How to's" will also help, here is the Link I searched it for you.

enjoy!

Oh Hi, That was fast~!!!

Thanks you for the info.

Was wondering where can I buy those items? as in the complete set?

Please re-read my first comment again - I have updated it.

you can find it on Amazon or Ebay easily, Just try to do separate search for an items HC-SR04 , Arduino Uno , USB Cable , Few Male to Female jumper wires.

Ok, thank you very very much.
