3.3-5V 3-Wire Vibration Sensor Module (ARD114E)

SW-18010P Vibration Sensor Module – LM393

The SW-18010P Vibration Sensor Module is designed to detect vibration, movement and shock. It uses a sensitive SW-18010P vibration sensor together with an LM393 comparator to provide a clean digital output signal.

Ideal for alarm systems, vibration detection, security projects, Arduino projects and other DIY electronic applications.

Features

• Sensor: SW-18010P vibration sensor
• Comparator: LM393
• Operating Voltage: 3.3V – 5V DC
• Output: Digital HIGH/LOW signal
• Output drive capability: More than 15mA
• Adjustable sensitivity via onboard potentiometer
• Onboard vibration/output indicator LED
• Mounting hole for easy installation
• Compact PCB size: 32mm × 14mm
• Suitable for connection to Arduino and other microcontrollers

Pin Connections

• VCC: Positive power supply (3.3V–5V)
• GND: Negative / Ground
• DO: Digital output
• AO: Not functional with the SW-18010P vibration sensor

How It Works

When no vibration is detected, the vibration switch remains open and the DO output is HIGH. The green indicator LED remains OFF.

When vibration or shock is detected, the sensor momentarily activates and the DO output changes to LOW. The green indicator LED turns ON.

The digital output can be connected directly to a microcontroller input, allowing your circuit to detect vibration and activate an alarm, buzzer, LED or other response.

Applications: Security alarms, anti-theft projects, vibration detection, shock detection, DIY electronics and educational projects.
