Features:
1. All kinds of our sensitive vibration switch, default SW-18015P vibration sensor.
2. Comparator output, clean signal, good waveshape, strong driving ability, more than 15 mA.
3. Operating voltage: 3.3V, 5V
4. Output form: Digital switch output (0 and 1).
5. Easy to install with fixed bolt holes
6. PCB board size:3.2cm X 1.4cm
7. LM393 Wide Voltage Comparator
Module interface description (3 wire)
1. VCC external 3.3V-5V voltage (can be directly connected to 5V and 3.3V)
2. GND External GND
3. Small board digital output interface (0 and 1) modules operation
Module power indicator will light up when VCC and GND are connected.
Adjust the blue potentiometer on the board until the onboard switch indicator light is placed on the desktop, then slightly call back potentio, so switch indicator light off, then hand hit the desktop so that the vibration sensor shock, indicator light will be in the light state. Switch indicator light will turn off for vibration stop. This phenomenon is that the vibration can result in the switch indicator light can trigger the module.
Module Connection Details:
1. VCC: Connected power source correct
2. GND:Connection power supply negative
3. DO:Digital signal output
Application:
So it is used for all kinds of trigger vibration, theft alarm, intelligent automobile, electronic building blocks.
Please note that the trigger time is short when small vibrations are induced and not enough to drive the relay, according to some people, it can be directly connected to the relay module, and the actual effect is not good enough.
Package includes:
5 x Vibration Sensor Module
