Vibration sensor module Normally closed type alarm module vibration induction switch SW-420

The Vibration Sensor Module Vibration Switch SW-420 is based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. When this no vibration, this module output logic LOW the signal indicate LED light, and vice versa. Features of The Vibration Sensor Module Vibration Switch SW-420: Normally closed type vibration sensor SW-420 The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma The working voltage of 3.3V to 5V Output form: digital switch output (0 and 1) Has a fixed bolt hole, convenient installation Small board PCB size: 3.2cm x 1.4cm Use the LM393 wide voltage comparator Package Includes: 1 x The Vibration Sensor Module Vibration Switch SW-420
