Tilt Sensor: Easily Check and Adjust Frame Alignment

Smartphone Tilt Sensor for Perfect Frame Alignment

In this project, we will create a tilt sensor using Protobject, a web-based platform. This tool helps you check and adjust the alignment of a frame using just a smartphone—no extra sensors or hardware required.

Protobject leverages your smartphone’s built-in orientation sensor to measure tilt angles and provide real-time visual feedback through color-coded indicators.

1. 1 Smartphone (used as a tilt sensor)
2. 1 Frame (to be aligned)
3. Internet Access (to use the Protobject platform online)

1. Visit the Protobject platform at https://app.protobject.com using Chrome or any Chromium-based browser (e.g., Edge, Opera).
2. You can start using Protobject immediately, without the need to sign up or log in.

1. Add the Inclination device by opening it on your smartphone.
2. Add the Lamp device on the same smartphone by using the Scan option visible once the Inclination device is opened. This device provides visual feedback based on the tilt angle.

How It Works

The prototype runs in an infinite loop to continuously monitor the tilt angle.

The system measures the tilt on the Y-axis using the smartphone’s orientation sensor.

The tilt value determines which color light is activated:

1. Green Light (Tilt < 6°): The frame is properly aligned.
2. Yellow Light (Tilt 6°-19°): Minor tilt, slight adjustment needed.
3. Orange Light (Tilt 20°-39°): Significant tilt, requires correction.
4. Red Light (Tilt ≥ 40°): Excessive tilt, immediate adjustment required.

This color-based feedback system allows users to quickly and precisely align their frames.

The code is already prepared for you! You can view it in detail at this link. Comments are included to provide clarification when needed.

You can also open the project directly in Protobject to avoid manually setting it up.

1. Place your smartphone on the frame.
2. Adjust the frame’s position while monitoring the light color.
3. Stop adjusting when the green light appears, indicating a perfectly level frame.

Add Sound Alerts: Integrate the MusicalKeyboard component to play a sound when excessive tilt is detected.

Improve Calibration: Fine-tune the calibration to achieve more accurate leveling and better responsiveness to slight tilt changes.

By using Protobject’s web interface and your smartphone’s built-in sensors, you’ve created a practical and precise tilt sensor without needing extra hardware.

You can enhance this tool further by integrating additional smart features or expanding its functionality for other leveling tasks.

Happy aligning!
