Watchport Water Sensor Stand

Build a Stand for Your Watchport/W Sensor Using Office Supplies!

When we first began using the Watchport water sensor, we needed a way to keep it level on the ground so that the leads could effectively detect water. This was my solution and I thought I’d share because it is cheap, effective and easy. To start, you’ll need the following supplies, which you can find around almost any office (aside from the sensor, of course).

Supplies You’ll Need:

  • 1 Watchport/W Sensor
  • 1 Drill. If you don’t have one of these don’t worry, just grab a small, sharp, flat-head screwdriver and we’ll improvise!
  • 3 small screws. I prefer wood or sheet metal screws because of the pointy tip, but whatever you have lying around the office should be fine
  • 1 screwdriver (whichever type matches your screws)
  • 1 CD. I know you have a stack of old driver CDs you’ll never use, grab one! The CD that ships with the sensor also happens to work great, and everything on it you can get online. Just be aware that some CDs can be a little brittle – if it starts to shatter when you cut it, get a different CD.
  • 1 sharp, nice pair of scissors. The sharper and nicer the better.

Oh, and don’t throw away this foam pad just yet, it’s conductive so you can use it to test your sensor later on:

Alright, let’s build it!

1.  Make guide marks on your CD.

You’re cutting three small “feet” which will come out from the center of the disc.

2. Cut out the Stand

Go ahead and cut out the excess plastic with your awesome scissors to make something similar to this:


3. Drill the Holes

Time to drill the holes. Drill two a few centimeters from the edges. For the last one, place the sensor on the mount closer to the center, in a manner similar to that pictured below, and mark the hole with a pen. Always make the holes a little smaller than the screw you’re using. If the sensor pins are too thin to fit around the leg, just cut two small divots in the sides of the leg to allow the pins to pass around it unhindered.

Note: if you don’t have a drill, you can whittle away holes in the CD by twisting an angled flat-head screwdriver repeatedly over one spot:

It’s not super fun, or super effective, but it’ll work in a pinch. It will work best if you don’t drill through all the way and let your screws finish out the last of the hole.

4. Screw the Screws

Now turn your CD stand so the shiny side is facing up, and screw your screws into two of the holes. For the last hole, screw the water sensor in with the screw. Adjust all screws to match the height of the sensor pins, so that when your stand is placed, the pins just barely touch the ground, and touch the ground evenly:

You’re all done! Once you’ve done a few you should be able to crank one out in under 10 minutes. Roll these out on the floor of your server room or datacenter away from walking paths and you will be able to detect significant water spills with relative ease. Happy monitoring!
