How can I make a sensor that will turn off my dust collector when the bin is full?
I am installing a cyclone dust collector in my workshop, and I want to make a sensor that will determine when my dust bin is full so that the chips and dust won't overflow into the filters. I'm thinking garage door sensors could be blocked by sawdust rising into the transparent flex hose between the cyclone and bin, but I'm not sure how they work. I would use them to turn on a warning light and turn off the dust collector. Any ideas? I'm good with tinkering and basic electricity, but am stuck trying to figure this out.
