The Gold SW-520D Angle Sensor Module, also known as a ball switch, vibration switch, or tilt sensor module, is a simple sensor module used to detect the inclination or tilt of an object. Here are the specifications and features: 1. **Type:** Angle Sensor Module / Ball Switch / Vibration Switch / Tilt Sensor Module 2. **Sensor Type:** Ball switch 3. **Detection Principle:** The module contains a small metal ball that moves inside a tube with electrical contacts at either end. When the module is tilted or inclined beyond a certain angle, the metal ball makes contact with one of the electrical contacts, completing the circuit. 4. **Operating Voltage:** Typically operates at 3.3V or 5V (depending on the specific model and configuration) 5. **Output:** Digital output (high or low) indicating the tilt state 6. **Interface:** Usually comes with three pins (VCC, GND, and Signal) for easy connection to a microcontroller or other circuitry. 7. **Material:** Usually made of high-quality materials for durability and reliability. 8. **Mounting:** The module may have mounting holes or adhesive backing for easy installation. 9. **Application:** Commonly used in tilt sensing applications such as alarm systems, automotive applications, gaming controllers, and electronic toys. 10. **Dimensions:** Compact and easy to integrate into projects. 11. **Accuracy:** Generally provides a reliable indication of tilt or inclination, but the accuracy may vary depending on the specific application and environment. Please note that while the specifications provided here are typical for this type of sensor module, actual specifications may vary depending on the manufacturer and specific model of the product. It's recommended to check the product details provided by the seller or manufacturer for precise specifications before making a purchase.
