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.
