Good sensor, clear instructions needed
The hardware quality is solid and the LEDs make debugging easy. I deducted one star because it didn't come with a printed manual, but online examples are plentiful.

Perfect for Arduino projects
This module works flawlessly with my Arduino Uno. The sensitivity adjustment is very responsive, making it easy to calibrate for specific tilt angles. Great value for the price.

Great for learning electronics
Bought this for a university project on orientation sensing. It was easy to interface and the digital output saved me from dealing with analog noise issues.

Compact and functional
Small footprint fits well in tight enclosures. Works as advertised. Just ensure you provide a stable 5V supply for consistent triggering.

Reliable vibration detection
I used this to create a simple vibration alarm for my toolbox. It triggers instantly upon movement. The build quality feels durable enough for long-term use.

Excellent sensitivity control
The potentiometer allows for fine-tuning which is crucial for my application. No false positives once calibrated correctly. Highly recommended.
Q: Is this compatible with Raspberry Pi GPIO pins?
A: Yes, it is fully compatible. You can connect the VCC to a 3.3V or 5V pin, GND to ground, and the Digital Output (DO) to any GPIO input pin.
Q: Can this module detect 360-degree rotation?
A: No, the SW-520D is a tilt switch designed to detect changes in angle relative to gravity or vibration events, not continuous 360-degree rotational position.
Q: Does this output analog or digital signals?
A: This specific SW-520D module outputs a digital signal (HIGH or LOW). If you need analog data regarding the degree of tilt, you would require an accelerometer module instead.
Q: How do I adjust the sensitivity of the sensor?
A: There is a blue potentiometer on the board. Use a small screwdriver to turn it clockwise to increase sensitivity or counter-clockwise to decrease it while testing the output state.
Q: What is the maximum current consumption of this module?
A: The module typically consumes less than 5mA during operation, making it suitable for battery-powered applications.
