Laundry Detection! Easily detect when your washing machine cycle ends

3D Printing and CNC Machining at PCBWay - www.pcbway.com/setinvite.aspx...
In this video, I'm showing two options that one can take to implement a laundry cycle ending detection in their smart home setup.
One of the routes is to implement a vibration sensor to detect the vibrations produced by the washing machine and once the vibrations have stopped, it will alert us that the cycle has completed.
Another approach is to use some of the LEDs already on the machine and an LDR to detect if they are lit so we can know that a certain state has been achieved.
Finally, I also glimpse over some other options with power metering power plugs or current clamps that can be added to the machine for power consumption detection.

nice an effective project

[@TasteTheCode]

Thanks!

[@steven_porter]

Depending on the frequency of the noise vs signal for the piezo, a high pass or low pass filter could help a lot. My gut says that a low pass would be the way to go since the movement of the machine would be relatively low frequency (under 100hz) while noise from the piezo likely is much higher

[@TasteTheCode]

Cool, thanks for the suggestion. I'll try to add one next time I play with the piezo and see how it behaves.

My washing machine make's a full opera music when finished 😂

[@TasteTheCode]

Hahahhahhahha that's funny.

[@davidjobe9876]

Nice ;)
I thought a Piezo can only make music, didn't know it can also detect movement.

[@TasteTheCode]

Yup, they are very often used as pickup in an acoustic guitar to connect them to amplifiers. I want to try that one day.

[@Tntdruid]

A ZigBee smart plug is what i use and HA 👍

[@TasteTheCode]

Cool. What wattage you have the plug rated at?

[@Tntdruid]

@@TasteTheCode 20A and 4800W, machine only peak at 2300W.

[@SlavkosHobbyChannel]

Interesting!

[@TasteTheCode]

Thanks! Glad you think so!
