ALLNET 4duino Vibration Sensor Analog/Digital (ALL_OY_3444)

The ALLNET 4duino Vibration Sensor (ALL_OY_3444) is a versatile analog and digital vibration detection module designed for Arduino, Raspberry Pi, ESP32, and other microcontroller platforms. It features the SW-420 spring-type vibration switch and an LM393 comparator for adjustable sensitivity, making it ideal for motion, shock, and vibration sensing projects.

Advantages

Dual output (analog and digital) provides flexibility for different applications. Onboard potentiometer allows easy sensitivity adjustment. Compact design with M3 mounting hole simplifies integration. Low quiescent current (<10mA) ensures energy efficiency.

Suitable for

• Vibration and shock detection in security systems
• Motion-activated lighting or alarms
• Industrial equipment monitoring
• Educational electronics projects

Key specifications

• Sensor Type: Vibration Sensor (SW-420)
• Output Type: Digital (DO) and Analog (AO)
• Operating Voltage: 3.3V - 5V DC
• Comparator Chip: LM393
• Adjustable Sensitivity: Yes, via onboard potentiometer
• Indicator LEDs: Power LED, Digital Output Status LED
• Interface Pins: 4-pin header (VCC, GND, DO, AO)
