ALLNET 4duino modul senzora vibracija (ALL_OY_3222-1)

The ALLNET 4duino Vibration Sensor Module (ALL_OY_3222-1) is a compact and reliable digital vibration detection module designed for Arduino, Raspberry Pi, and other microcontroller projects. Based on the SW-420 vibration sensor and LM393 comparator, it provides a clean digital output signal when vibration is detected, making it ideal for alarm systems, motion detection, and impact sensing applications.

Advantages

Easy to integrate with any 3.3V or 5V microcontroller thanks to its digital TTL output. The onboard potentiometer allows you to adjust the sensitivity threshold to suit your specific application. Low power consumption and fast response time ensure reliable performance in battery-powered or real-time systems.

Suitable for

• Vibration and shock detection in security systems
• Motion-activated lighting or alarms
• Impact sensing for robotics and automation
• Educational projects with Arduino or Raspberry Pi
