The GY-25 Tilt Angle Sensor Module is a dedicated inclination measurement device that utilizes a sophisticated 6-axis motion processor to provide highly accurate, pre-processed tilt data via a simple serial interface. This module simplifies the process of measuring precise pitch and roll angles, ideal for applications in robotics, stability control systems, and automation.
Product Description
The GY-25 Tilt Angle Sensor Module differentiates itself from raw Inertial Measurement Units (IMUs) by integrating a powerful microcontroller that runs sensor fusion algorithms internally. This means you do not receive raw accelerometer and gyroscope data; instead, the module outputs calculated, stable pitch and roll angles directly in degrees via its UART (Serial) port. This plug-and-play approach significantly reduces the programming complexity and computational load on your main microcontroller (like an Arduino, STM32, or Raspberry Pi).
The module is specifically optimized for stability and minimal drift in static and dynamic environments. The serial output provides clean, digital data that is easier to use than analog signals and typically offers higher precision. Operating with a flexible power range of 3V to 5V, the GY-25 is a versatile and efficient solution for engineers and hobbyists seeking a straightforward way to incorporate precise inclination sensing into their projects.
Key Features
  • Pre-processed Angle Output: Directly outputs stable Pitch and Roll angles in degrees via serial communication.
  • Internal Sensor Fusion: Onboard processing unit runs complex algorithms to minimize drift and stabilize readings.
  • Simple Serial Interface: Uses standard UART communication (TX/RX) for easy integration with any microcontroller.
  • Wide Voltage Compatibility: Built-in LDO regulator allows operation from 3V to 5V power supplies.
  • High Precision: Offers fine resolution of approximately 0.01 degrees.
  • Selectable Baud Rate: Supports common baud rates (e.g., 9600 or 115200 bps) typically via a solder jumper or command.
  • Compact Form Factor: Small PCB size ideal for embedding within devices and prototypes
Usage
The GY-25 module is used wherever a simple, reliable angle measurement is needed:
  1. Robotic Arms: Ensuring precise positioning and orientation of end effectors.
  2. Platform Stabilization: Keeping a camera platform or solar panel level.
  3. Level Monitoring: Industrial or agricultural equipment angle monitoring.
  4. Gesture Input: Simple pitch/roll based human-machine interaction systems.
To use the module:
  • Connect VCC to 5V/3.3V and GND to common ground.
  • Connect the module’s TX pin to your microcontroller’s RX pin.
  • Connect the module’s RX pin to your microcontroller’s TX pin (if you need to send configuration commands).
  • Use your microcontroller’s Serial library to read the incoming data packets.
Q: Do I need to write complex sensor fusion algorithms myself?

No, that is the main advantage of the GY-25. The angle calculation is performed onboard, and you simply read the final angle data via the serial port.

Q: What is the output data format?

The module typically outputs structured data packets containing the pitch and roll angles in degrees, which you can parse with simple serial reading code.

Q: Can I get raw accelerometer data from this module?

No, this module is configured to only output processed angle data. If you need raw data, you should use the standard MPU-6050 GY-521 breakout board.

Q: Is the module compatible with 5V logic systems like Arduino Uno?

Yes, the serial communication pins are 5V tolerant, and the power input accepts 3V to 5V.

Q: Can I measure Yaw (heading/compass direction) with this module?

No, this module only measures Pitch and Roll relative to gravity. Yaw measurement requires a magnetometer (compass sensor), which is not integrated into the GY-25.
