Things I want to make: A Flood Sensor

[danychouinard]

Once I figured why I cannot make my gateway to work, this would be something I want to do :

or for a melodramatic video : www.youtube.com/watch?v=8JRxUoHbEN8

Pretty sure that this would be quit easy to build.

Yes, danychouinard, it's enjoyable to dream home automation applications & pursue them to completeness.

Here's some hints on how you might start on your flood-sensor.

     Leak Detector Node

To achieve a self-contained unit, you might use one of these small Arduino compatibles with installed RFM69 radio: an Anarduino Miniwireless or a lowpowerlab.com Moteino.
Then work out battery power for that compatible. Some of our forum threads cover using Arduino sleep functions to maximize battery life.

Not having the sensor probes powered all the time would decrease the probe's electrolysis.  (Power the probe with an Arduino digital pin that code turns on & off.)

Between Arduino code & OpenHAB code, the temperature programming of the flood sensor should be possible.

Forum threads also document having OpenHAB send notices. I use those in my system.

Having everything (except the probes) inside a waterproof, but functional case that is not too big could be challenging.

Sounds like a neat project that I'd love to see documented on this forum.
