Vibration Sensor Switch Module SW1801P

Description

 SW1801P Vibration Sensor Module – High‑Sensitivity Tilt & Vibration Switch

This compact and reliable vibration sensor module is designed to detect movement, tilting, or shaking and output a clean digital signal for your microcontroller . Inside, it uses a ball‑rolling type of sensor (not mercury‑based) that triggers a switch when it moves — perfect for a wide range of alarm, automation, and robotics applications .

A built‑in LM393 comparator ensures stable output, and the module comes with both a power LED and a status LED for easy visual feedback . An onboard potentiometer lets you adjust the trigger sensitivity to suit your needs .

How It Works

• When the module is not vibrating, the internal switch is open, the output is HIGH, and the green indicator LED is OFF .

• When a vibration or tilt occurs, the switch momentarily closes, the output goes LOW, and the green LED lights up .

You can connect the DO pin directly to a microcontroller to detect these level changes and trigger an alarm, a notification, or any other action .

Perfect For

• Vibration‑triggered alarms and security systems

• Theft‑detection and anti‑tamper devices

• Smart cars, robotic motion sensing, and electronic building blocks

• Tilt and orientation detection in projects

Important Note

For very small shocks, the trigger time can be extremely short — often not long enough to directly drive a relay. Using a microcontroller to read the signal is strongly recommended .
