Vehicle Vibration Logger Kit: Arduino Uno & SW-420 Sensor - Car Security Alarm System

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform a parked car into a tamper-proof zone. This kit uses the SW-420 vibration sensor to detect subtle knocks on windows or doors, triggering a loud buzzer and flashing LED while logging each event to the Arduino serial monitor.

What You'll Build

A working vehicle vibration alarm that mounts on a car door or window. The SW-420 sensor triggers a loud buzzer and flashing red LEDs when vibration is detected. The Arduino logs each event with a timestamp, giving you a tamper record.

What You'll Learn

• How vibration sensors work and how to calibrate sensitivity thresholds with a potentiometer (on SW-420)
• Writing Arduino code to read analog/digital sensor signals and trigger multiple outputs
• Building a real-world security alarm circuit with active buzzer and visual alert LEDs
• Serial data logging and basic event time-stamping for diagnostics
