I’m working on a DIY state detection for my dryer and have some questions.
I’ve seen suggestions to use a vibration sensor for this, so purchased and connected an SW-420 vibration sensor to an ESP8266. Unfortunately, this does nothing for me. Not sure if my dryer runs too smoothly but it does not detect any vibration from my dryer. I’ve adjusted the potentiometer on it, but still no luck. I have to give the sensor a tap in order for it to register anything. Is this the expected detection level for this sensor?
Does anyone recommend a different vibration sensor, or does the one I have not seem to be functioning properly?
My dryer runs on 220v as I am in Canada If it were 110 I would just use a power meter for it like I have for my washer.
To get dryer detection for the time being I’ve rigged up a micro switch to dryer and added a small 3d printed pointer the the timer knob located in the “done/off” position. It is very ugly and crude as I just used clear tape to attach the pointer and the micro-switch to the dryer but it works for now, until something better can be out in place.
Thanks in advance for any suggestions!
