It connects to the Raspberry Pi through the CSI interface and is ideal for photography, video streaming, machine vision, and embedded camera projects.

Key Features

5-Megapixel Sony IMX219 Sensor

  • Delivers sharp, high-quality still images.

  • Excellent colour accuracy and clarity.

Full HD Video

  • Supports:

    • 1080p @ 30fps

    • 720p @ 60fps

    • 480p @ 90fps

CSI Interface

It outputs a digital signal (HIGH or LOW) when vibration is detected.

The onboard 10KΩ potentiometer (preset) allows you to adjust the vibration sensitivity threshold. The LM393 comparator compares the voltage from the vibration sensor and the preset reference voltage, triggering a digital output when vibration exceeds the threshold.

This module operates on 3.3V to 5V, making it compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers. It includes onboard LED indicators for power and signal output, plus a mounting hole for easy installation in various enclosures or control panels.

Key Features:

  • Operating Voltage: 3.3V – 5V

  • Output Type: Digital (0 or 1)

  • Adjustable sensitivity using onboard potentiometer

  • LM393 wide voltage comparator for stable output

  • Power and signal indicator LEDs

  • Operating Current: ~15mA

  • PCB Size: 3.2 cm x 1.4 cm

  • Mounting Hole for easy installation

Applications:

  • Security and vibration detection systems

  • Earthquake or motion sensing projects

  • Smart alarm systems

  • Motor vibration monitoring
