mikroBUS Vibra sense click

Vibra sense click is a low cost micro shock vibration sensor with a digital output which can be set as an Interrupt.

Pins marked NC are not used. Only four pins marked red rectangle are available to use the module.

An expantion board for mikroBUS click modules helps you to place a click module on PHPoC Blue easily.

This example uses WebSocket to show sensor's output.
