Power Rating: Operates at 3.3V–5V DC – compatible with most microcontroller platforms like Arduino, ESP32, and Raspberry Pi.

Type: SW-520D Tilt Angle Sensor Module – detects changes in orientation or tilt position using a simple ball switch mechanism.

Working Principle: The internal metallic ball moves to make or break contact when the module is tilted, generating a digital signal output.

Output: Digital output (high/low) that can be directly read by microcontroller input pins without extra circuitry.

Sensitivity: Detects even slight changes in angle or movement, depending on installation orientation.

Build Quality: Features a robust PCB with stable components and an onboard status LED for easy operation monitoring.

Operation: Simple plug-and-play design with 3-pin interface (VCC, GND, DO).

Applications: Ideal for motion detection, orientation sensing, anti-theft alarms, robot balance systems, and smart automation projects.
