Vibra Sense click is a low cost micro shock vibration sensor with a digital output which can be set as an Interrupt (mikroBUS INT pin) An onboard potentiometer lets you set the interrupt threshold. An additional Enable line (EN) is in place of the mikroBUS pin. It’s a very simple and effective solution for detecting vibrations. The sensing unit consists of a round housing in which a spring is coiled around a metal pin. When exposed to vibration, the spring contacts the pin and closes the switch. The board is designed to use either a 3.3V and a 5V power supply.
