This normally open vibration sensor module is for a variety of vibration trigger functions, reported theft alarms, smart cars, electronic building blocks, and so on. Please note that the normally open vibration sensor module in the induction of a small vibration when the trigger time is very short is not enough to drive the relay; some of the information displays can be directly connected to the relay module, but the actual use is ineffective.
When the product does not shake, the vibration switch is held in the off state, the output is high, and the green light does not shine. When the product vibrates, the vibration switch goes into momentary conduction mode, the output end of the output goes low, and the green indicator light lights 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 and play an alarming role.
Connection
VCC: Connect the positive power supply
GND: Connect to the negative power supply
DO: The digital signal output
