Washing machine monitor

accelerometer based washing machine monitor

A really cool post written by Genius Devil (Viktor) about making his own washing machine..
He has gone for a non destruction method to detect whether  the washing machine is working or not obviously he was not in mood to loose his warranty.

So he used a PIC microcontroller and an accelerometer to detect vibrations.He has not declared his algorithm, but we can guess that he is firstly reading the accelerometer data and after some time he again take the reading if both are same that indicates the washing machine has stopped otherwise washing machine is vibrating in random fashion..

When the washing is finished the device will sound a buzzer.

There are many other techniques suggested to him about alternatives to this on comments of his blog.
