SW520D Tilt Sensor Module – Vibration and Angle Detection
SW520D Tilt Sensor Module – Vibration and Angle Detection
The SW520D Tilt Sensor Module is a vibration and angle detection switch that outputs a digital signal when tilted. Commonly used in orientation detection, alarm systems, and robotics, it provides a simple interface for detecting movement or change in position. With a built-in comparator, it offers clean digital output for microcontrollers like Arduino and Raspberry Pi.

- Orientation detection for robots (e.g., fall detection)
- DIY motion-activated light or sound
- Angle sensing for solar tracker projects
Compatibility
Works with any 3.3V or 5V microcontroller, including Arduino Uno, Nano, Mega, ESP8266, ESP32, and Raspberry Pi (with proper level shifting if using 3.3V logic). The digital output can be directly connected to a GPIO pin. The module includes an onboard pull-up resistor, so no external components are required for basic operation.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to ground, and DO to a digital input pin. The output goes LOW when tilted, HIGH when upright. For noisy environments, add a small capacitor (0.1µF) between DO and GND to debounce the signal.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the SW520D module works directly with Arduino Uno. Connect VCC to 5V, GND to GND, and DO to any digital pin (e.g., pin 2). Use digitalRead() to detect tilt.
What is the typical response time?
The tilt switch responds within milliseconds when the orientation changes beyond the threshold angle. The ball inside makes contact quickly, suitable for real-time detection.
Can it detect vibration, not just tilt?
Yes, the SW520D can sense vibration by detecting rapid changes in tilt. It’s suitable for simple vibration alerts but not as sensitive as a dedicated accelerometer.
