Jaco Pieterse Posted August 18, 2021 Report Share Posted August 18, 2021 Good day, What is the smallest vibration or sound vibration sensor/switch known to activate a pulse or send a signal or close a contact. I'm currently working on a project to detects vibration to then switch a light on. ( Battery powered 12v ) example: Whenever I hit my drums with a drum stick a light must come on. Limited space Thank you. Quote Link to comment Share on other sites More sharing options...
0 DrD Posted August 18, 2021 Report Share Posted August 18, 2021 An accelerometer should do the trick. Quote Link to comment Share on other sites More sharing options...
0 G B Reid MIMechE, SIMarEST Posted August 31, 2021 Report Share Posted August 31, 2021 Failing the accelerometer - which would be very successful if on a drum - you could connect a microphone to a transistor to switch on the light. It is a very simple circuit and is reproduced on a number of differing electronics websites. Basically the "switch" would be the microphone. They generally have a resistor in the circuit...if this was a variable resistor, it could be adjustable. daisy chain this to a timer circuit and you're laughing....or drumming! Good luck!
