30 in stock



  • SW-420 Motion Sensor Module
  • Condition: New
  • Purpose:
  • Used to trigger the effect of various vibration, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc.
  • This module is compared with the normally open type vibration sensor module, vibration trigger for longer periods of time, can drive the relay module
  • Module features:
  • 2. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma
  • 3. The working voltage of 3.3V to 5V
  • 4. Output form: digital switch output (0 and 1)
  • 5. Has a fixed bolt hole, convenient installation
  • 6. Small board PCB size: 3.2cm x 1.4cm
  • 7. Use the LM393 wide voltage comparator
  • Module directions for use:
  • 1. Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
  • 2. Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright
  • 3. Output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, call the police
