This Normally open vibration sensor module is for a variety of vibration trigger function, reported theft alarm, smart car, electronic building blocks and so on. Please note that Normally open vibration sensor module in the induction of a small vibration when the trigger time is very short, not enough to drive the relay, some of the information display can be directly connected to the relay module, the actual use of ineffective.

When the product does not shake, the vibration switch is held in off state, the output is high and the green light does not shine and when the product vibrates, the vibration switch goes in momentary conduction mode, the output end of the output goes low and the green indicator light-up.

Output can be directly connected to the microcontroller through the microcontroller to detect high and low levels, thus to detect whether there is a vibration of the environment, play an alarming role.
