Product Purpose

Used for various vibration triggering functions, theft alarm, smart cars, electronic building blocks, etc.

Please note that this module has a short triggering time when sensing small vibrations, which is not enough to drive the relay. Some people's data shows that it can be directly connected to the relay module, but the actual application effect is not good.

Product Features

1. Using various sensitivity vibration switches produced by our company, the SW-18015P vibration sensor is used by default,.

2. Comparator output, clean signal, good waveform, strong driving capability, exceeding 15mA

3. Working voltage 3.3V-5V

4. Output format: Digital switch output (0 and 1)

5. Equipped with fixed bolt holes for easy installation

6. Small PCB size: 3.2cm x 1.4cm

7. Using a wide voltage LM393 comparator

Product Use

Module interface description (3-wire system)

1 VCC external 3.3V-5V voltage (can be directly connected to 5V and 3.3V microcontrollers)

2 GND external GND

3 DO small board digital output interface (0 and 1)

Connect VCC and GND, the module power indicator light will light up

Gently place the module on the desktop, adjust the blue potentiometer on the board until the switch indicator light on the board is on, then slightly adjust the potentiometer to turn off the switch indicator light, and then tap the desktop with your hand to make the vibration sensor vibrate. At this point, the switch indicator light will return to the on state. The vibration stops and the switch indicator light will also turn off. This phenomenon indicates that vibration can trigger the module, causing the switch indicator light to light up.
