Reliable and compact

I bought five of these for a robotics balance project. They are very compact and the mounting holes make them easy to secure. The response time is fast, which is critical for my application.

Good value, clear instructions needed

The module itself is high quality and the LEDs are bright enough to see status clearly. It took me a moment to figure out the pinout without a diagram, but once connected to 5V, it worked instantly. Great for beginners.

Works well with 12V too

Tested this with both 5V and 12V inputs as advertised. No issues with either voltage. The output signal is clean digital, making it easy to interface with microcontrollers without extra conditioning.

Great for learning electronics

Bought this for a university prototype. It helped me understand how tilt switches function in real-world circuits. The dual LEDs are a nice touch for debugging logic states visually.

Perfect for my Arduino project

This tilt sensor works exactly as described. The sensitivity is easy to adjust with the small blue potentiometer. I used it to create a simple alarm system for a model safe, and it triggers reliably every time.

Sturdy construction

Unlike some cheaper sensors I've tried, the soldering on this board is clean and the components feel secure. The rolling ball mechanism inside is smooth. Highly recommend for educational kits.

5 FAQ

Q: How do I adjust the sensitivity of the tilt detection?

A: There is a small blue potentiometer on the board. Use a small screwdriver to turn it clockwise or counter-clockwise while tilting the module until the red LED triggers at your desired angle.

Q: Is the output normally open or normally closed?

A: The default state depends on the orientation and adjustment. Typically, the output goes HIGH when the tilt threshold is exceeded and LOW otherwise, but this can be inverted by changing your code logic or physical mounting.

Q: Does this module work directly with a 3.3V microcontroller?

A: While the module supports 5V and 12V input, the output signal will be at the input voltage level. If using a 3.3V MCU with a 5V supply, you may need a logic level converter or a voltage divider on the output pin to prevent damage.

Q: What is the maximum current this module can handle?

A: The output pin is designed for signal logic levels and should not be used to drive high-current loads directly. Please use the output to trigger a transistor, relay, or MOSFET if you need to control higher power devices.

Q: Can this sensor detect vibration or only static tilt?

A: This is primarily a tilt switch based on a rolling ball. While strong vibrations might trigger it accidentally, it is designed for detecting changes in angle rather than measuring vibration frequency or intensity.
