Normally open vibration sensor module


  • The use of wide voltage LM393 comparator.
  • Using the company‚Äôs high-sensitivity vibration switch, the default with SW-18015P vibration sensor.
  • The comparator output, the signal clean, good waveform, driving ability, more than 15mA
  • With a fixed bolt hole, easy to install.

Normally open vibration sensor module is for a variety of vibration trigger functions, reported theft alarm, smart car, electronic building blocks, and so on. 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 into momentary conduction mode, the output end of the output goes low and the green indicator light-up.

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. 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.


  • VCC: Connect the positive power supply
  • GND: Connect to the negative power supply
  • DO: The digital signal output
