I want my shop vac to turn on whenever I turn on a loud power tool in my shop. I thought it would be interesting to trigger it with sound using this microphone sensor.
It seems pretty straight forward to activate the shop vac with the sensor and a relay. I was thinking myself quite clever for the idea but then got stumped on how to deactivate the relay when the tool turns off. At that point the shop vac will also be making a ton of noise and the sensor won't know the difference.
Any ideas to make this work? I'm open to using another method as well.
