Homemade DIY Basement Water Sensor Hack!
Intro: Homemade DIY Basement Water Sensor Hack!
Quickly and easily hack a smoke detector into a basement, sump pump water sensor,
Materials needed
1.) New/Used smoke detector with a test button
2.) Soldering kit
3.) Wire
4.) Wire cutters / strippers
4.) Duct Seal (or other non-conductive adhesive
STEP 1: Add Your Wires
Remove the cover to the smoke detector, you should be able to find where and how the test button works. Next take 2 pieces of wire any length and solder them to each contact point of the test switch.
*TIP* (once soldered touch and hold the other ends of the wire together for a few seconds to verify that it works)

STEP 2: Finish
I used Duct seal to hold the wires together, it's tacky, waterproof, and non-conductive.
Encase the wires in a gob of duct seal and place wherever you want the alarm to go off when water is present.
Retest again by splashing some water over both contact points to confirm operation.
You're all set!

This is great and works.. a possible tip regarding fire alarm sound, I don't know if they all the same but I have UK smoke alarm with 3 wires going to sounder ( red white black) I cut the white one and this lowered the pitch of the sound so it has it's own distinctive sound rather than exactly like smoke alarm.

Great! I have needed something like this for a while. It's like my own EASY button. Thank you. I just love all the great solutions to life's problems I have found on this site. What I don't understand though is why someone always manages to post a retail solution in the comments. This site is for D.I.Y. !!

Yeah... just keep in mind that the sensor in the smoke detector is RADIOACTIVE. So, you may want to avoid this project altogether.

Simple so far, but??? what battaries to use as standby? Normal car or deep discharge?? And should they be on trickle charge all the time?? Since they would be seldom used? I can't seem to find info about which would last the best??
Look forward to comments or emails??
