Frequently Asked Questions

Q: What does the SW-520D Angle Tilt Sensor Module detect?

A: The SW-520D Tilt Sensor Module detects changes in angle and vibration. When the module is tilted beyond a set threshold or experiences vibration, the internal conductive ball rolls and completes or breaks the circuit, sending a digital HIGH or LOW signal to your microcontroller.

Q: Which microcontrollers is the SW-520D sensor module compatible with?

A: The SW-520D Angle Tilt Sensor Module is compatible with virtually any 3.3V or 5V microcontroller, including Arduino (Uno, Nano, Mega), Raspberry Pi, ESP8266, ESP32, STM32, and similar platforms. Simply connect VCC, GND, and the digital output (DO) pin to get started.

Q: Can I adjust the sensitivity of the tilt sensor module?

A: Yes! The module features an onboard potentiometer that allows you to fine-tune the sensitivity threshold. This lets you control how much tilt or vibration is required to trigger the digital output signal, making it versatile across a wide range of project applications.

Q: What are common uses for the SW-520D Ball Switch Tilt Sensor?

A: Common applications include tilt-triggered alarms, anti-tamper detection, vibration-sensing circuits, position indicators, interactive toys, robotics balance detection, and DIY home automation projects.
