Price: $0.23Sku: FA3091
Product Introduction

SW-420 Normally Closed Alarm Vibration Sensor Module

Features:
1. using SW-420 normally closed type vibration sensor.
2. the comparator output signal is clean, good waveform, driving ability, more than 15mA
3. the working voltage of 3.3V-5V
4. the output format: digital switching outputs (0 and 1)
5. a fixed bolt holes for easy installation
6. small PCB board size: 3.2cm x 1.4cm
7. using a wide voltage LM393 comparator

Module for use:
1. no shock, vibration switch was closed conduction state, output of low output, the green indicator light;
2. shock, vibration switch instantly disconnected, the output-side output high, the green light does not shine;
3. the output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting whether the vibration environment, played the role of the police
