SW420 NC Type Vibration Sensor Module for Arduino

Description

• Using SW-420 normally closed type vibration sensor.
• Comparator output, clean signal, good waveform, strong driving ability, >15mA.
• Using a wide voltage LM393 comparator.
• With bolt holes for easy installation.

Note:

• Do not reverse the power directions, otherwise, it is possible to burn the chip.
• The signal LED light is output Low, signal LED OFF output is High.
• The output level is close to the input voltage.
