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.

Compact and functional

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

Excellent sensitivity control

The potentiometer allows for fine-tuning which is crucial for my application. No false positives once calibrated correctly. Highly recommended.

5 FAQ

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.
