vibration sensor - low voltage
Asked Oct 17, 2016, 02:11 PM
I'm building a Kaleidoscope with internal lighting. I have the lighting worked out with a manual switch, but I would prefer it to turn on with a sensor that detects that the kaleidoscope has been picked up. The light should stay on for 2 to 3 min. and go off when there is no activity for 2 to 3 min. Can you recommend a vibration sensor module or something else that will do this? Criteria: Cheap; very small (.75in cube or smaller); it will run on a 3v lithium button bat and power 1 LED bulb. Hopefully it will only use power when activated.
