Normally open; vibration sensor module; vibration switch; vibration sensor module; alarm module

Features : 1. high sensitivity vibration switch , default by SW-18010P vibration sensors . 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 wiring instructions : 1.VCC: positive power supply 2.GND: negative power connection 3.DO: digital signal output 4.AO: This vibration sensors with this function does not work Instructions for use: 1. the product does not vibrate, vibrate switch was disconnected state, the output -side output high , the green light does not shine ; 2. the product vibration, vibration switch instantly turns on, output of low output , the green indicator light ; 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.
