Build a Cheap Z-wave Vibration sensor?
-
Anyone been able to accomplish this?
Couldnt find anything in the listing.The idea is that i need a vibration sensor for each step on the stairway because i want to attach it to a LED that would light up each step indvidually as they sense motion / vibration.
But yet to find a "cheap" way to do this since prebuild vib sensors are like 50$ :/
Any ideas or tips would be greatly appriciated.
Hello, there are some very cheap accelerometers that should be able to do this job.
Check ADXL345 for example they cost 1$ on a breakout board on aliexpress. You should be able to put a few connected to the same pro mini board so you can manage more than one step and save even more. -
Why not using MySensors? Using one of these perhaps?

I've found those to be poor at detecting small vibrations, I doubt they will be reliable to detect someone putting foot on a step.

I haven't tried them myself. Does the piezo variant behave badly as well?

Haha interesting, never tried it. I'll order one right now to check, thank you for the link !

You can use all the free analog pins. In total 8 on AtMega328 (where 4 is easily exposed on a nano-board).

well i better get cracking then :) First project of this sort so we will see how it goes.

If it supports ethernet gateway then it's on the same network. Else it's serial gateway and you need to be connected with USB
