5pcs 3.3-5V 3-Wire Vibration Sensor Module Vibration Switch Alarm Module Geekcreit for Arduino - products that work with

Features 1 Use all kinds of sensitivity vibration switch produced by our company default SW 18015P vibration sensor 2 Comparator output clean signal good waveform strong driving ability more than 15mA 3 The working voltage 3 3V to 5V4 Output form digital switch output 0 and 1 5 Equipped with fixed bolt hole easy to install6 PCB board size 3 2cm x 1 4cm7 Use the LM393 wide voltage comparator Module interface description 3 wire 1 VCC external 3 3V 5V voltage can be directly connected with the 5Vand 3 3V 2 GND external GND3 DO small board digital output interface 0 and 1 module instructions When the VCC and GND are connected the module power indicator will light Put the module on the desktop adjust the blue potentiometer on the board until the on board switch indicator light and then slightly callback potentiometer so that the switch indicator light off and then beat the desktop by hand so that vibration sensor shock the indicator light will go to the light state Vibration stop switch indicator light will be off This phenomenon is that the vibration can trigger the module so that the switch indicator light Module connection details 1 The VCC connect power positive2 The GND connect power negative3 DO digital signal output Application It is used for all kinds of vibration triggering theft alarm intelligent car electronic building block and so on Please note that the trigger time is short when the small vibration is induced not enou
