Description

The Angle Sensor Module for Arduino SW-520D is a compact and efficient tilt detection module designed for projects involving motion or angle sensing. It integrates the SW-520D ball tilt sensor and LM393 comparator chip to provide accurate digital output signals that respond to changes in orientation. Featuring an adjustable sensitivity potentiometer, this module allows users to fine-tune its responsiveness for different environments. The digital output (0 for tilt, 1 for stable) makes it easy to interface with Arduino, Raspberry Pi, or other microcontrollers. With built-in power and output indicator LEDs, it provides visual feedback for quick diagnostics. Its simple 3-pin interface (VCC, GND, DO) and wide operating voltage range (3.3V–5V) make it ideal for use in safety alarms, robotic balancing systems, home automation, and DIY tilt-based control applications.

How to Use:

Wiring:

Connect VCC to a 3.3V-5V power source.
Connect GND to the ground.
Connect DO to the input pin of your microcontroller (e.g., P0.1).

Adjust Sensitivity:

Use the blue digital potentiometer on the module to adjust the sensitivity of the tilt sensor.

Output Reading:

When the angle switch detects tilt, the DO output will be low (0).
When there is no tilt, the DO output will be high (1).

Integration with Microcontroller:

Read the DO output to detect high/low levels via your microcontroller to monitor tilt events.

Direct Relay Control:

Connect the output to a relay module to drive high-power devices for tilt-based protection, such as automatic power-off functions.

Package Includes:

1 x Angle Sensor Module for Arduino SW-520D
