Great little sensor
Compact size fits perfectly into tight enclosures. The mounting holes are standard size which saved me some drilling. Very happy with the purchase for my home automation security sensors.

Stock up on these
We keep a bin of these in our makerspace because they are so versatile. From tilt alarms to orientation checks in RC cars, they handle everything we throw at them. Highly recommended.

Reliable and sensitive
I bought five of these for a robotics balance bot prototype. All five units performed consistently. The response time is fast, and the digital output makes interfacing with microcontrollers straightforward.

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

Works well for learning
Using this for a university embedded systems class. It's robust enough to handle student handling and provides clear signals. The only downside is the header pins were not pre-soldered, but that's expected at this price point.

Good value, clear instructions needed
The module itself is high quality and the LEDs make debugging very easy. However, it would be nice if there was a pinout diagram included in the package. Once I figured out the wiring, it worked great.
Q: Does this module provide an analog output or just digital?
A: This specific module provides a digital output (DO) which goes high or low when the tilt threshold is crossed. It does not provide an analog voltage proportional to the angle.
Q: Can I run this directly off a 3.3V logic level?
A: While the sensor can detect tilt at lower voltages, it is designed for 5V or 12V operation for optimal performance. For 3.3V microcontrollers, we recommend using a logic level converter or powering the VCC at 5V while connecting the DO pin directly, as the LM393 is open-collector.
Q: Is the detection angle fixed or can I change it?
A: The detection angle is fully adjustable. You can rotate the blue potentiometer on the board with a small screwdriver to set the sensitivity and the specific angle at which the switch triggers.
Q: What is the maximum current draw of this sensor?
A: The module typically draws less than 20mA when active, making it suitable for battery-powered projects. The standby current is significantly lower.
Q: Are the header pins included in the package?
A: Yes, a 3-pin male header strip is included in the package, though it is not pre-soldered to allow for flexible mounting options.
