801S Vibration Switch Detection Sensor Module – 3 Pin Vibration Sensor

801S Vibration Switch Detection Sensor Module – Reliable Shock and Vibration Detection for Arduino and IoT

The 801S Vibration Switch Sensor Module is a compact and cost-effective device designed to detect vibrations, shocks, and movements. It operates as a simple mechanical switch that closes or opens when vibrations exceed a certain threshold.

With its 3-pin interface (VCC, GND, and digital output), it easily connects to microcontrollers like Arduino, ESP32, and Raspberry Pi. This sensor is commonly used in security alarms, industrial machinery monitoring, and impact detection systems throughout Bangladesh.

Key Features:

• 3-pin interface: VCC, GND, Digital Output (DO)

• Operating Voltage: 3.3V to 5V

• Mechanical vibration switch sensor

• Digital HIGH when vibration detected, LOW otherwise

• Compact and lightweight design

• Easy to integrate with Arduino and other MCUs

Applications:

• Intrusion and anti-theft alarms

• Industrial vibration and machinery monitoring

• Impact and shock detection

• Smart home and IoT security systems

• Student and hobbyist electronics projects in Bangladesh

The 801S vibration sensor is a practical and affordable component for detecting mechanical vibrations and improving system safety in embedded applications.
