About this item

Uses: For a variety of shocks triggering, theft alarm, smart car, an earthquake alarm, motorcycle alarm. This module when compared with normally open penumatic shock sensor module, shock triggered much longer can drive relay module.

• Uses the company’s production of SW-420 normally closed type vibration sensors.
• Comparator output signal clean wave well, driving ability, 15mA.
• Rated voltage and 3.3V-5V output: digital switching output (0 and 1).
• Bolt-hole for easy installation.
• Small Board PCB dimensions: 3.2cm x 1.4cm.
• Uses wide LM393 voltage comparator.
• Module description: the product when it is not shock, vibrate switch is closed on-State, output output low level, the green indicator light is on.
