Frequently Asked Questions

Q: What is the SW-520D Tilt Angle Sensor Module and how does it work?

A: The SW-520D is a high-sensitivity ball switch tilt sensor module. It contains a small conductive ball inside a metal housing. When the module is tilted beyond a certain angle, the ball rolls and makes or breaks the internal circuit, producing a switching (ON/OFF) output signal. This makes it ideal for tilt detection, motion sensing, and orientation-based triggering in electronic projects.

Q: What projects is the SW-520D Tilt Sensor compatible with?

A: The SW-520D is compatible with a wide range of DIY electronics platforms including Arduino, Raspberry Pi, and other microcontroller boards. It is commonly used in robotics, security alarm systems, tilt-activated switches, smart home automation, toys, and STEM/educational prototyping projects. Its simple resistance-based switching output makes it straightforward to integrate with most digital input circuits.

Q: How many pieces should I order — 1, 5, or 10?

A: The right quantity depends on your project. A single piece (1PCS) is great for testing or a one-off build. Five pieces (5PCS) suit small batch prototyping or projects requiring redundancy. Ten pieces (10PCS) offer the best value for classroom use, larger robotics builds, or when you want spares on hand for ongoing development.

Q: Is the SW-520D sensor module made from durable materials?

A: Yes. The SW-520D tilt angle sensor is constructed from metal, providing solid durability for both prototyping environments and more permanent installations. Its metal housing protects the internal ball switch mechanism and ensures consistent electrical performance over repeated use.
