Product Information
Full details
The Seeed Studio Grove - 3-Axis Digital Accelerometer is designed for makers and developers looking to incorporate motion sensing into their projects, offering a straightforward way to measure acceleration up to ±16g. Its key benefit lies in its easy integration via an I2C interface and readily available libraries, simplifying data acquisition. A potential caveat for advanced users is its 10-bit resolution, which may limit precision in highly demanding applications.

Extended Product Information
FAQs
What is the measurement range of this accelerometer?
The sensor can measure acceleration up to ±16g along each of the three axes.
How does this sensor communicate?
It communicates using the I2C (Inter-Integrated Circuit) protocol.
Do I need a special board to use this sensor?
Yes, it is designed to work with the Seeed Studio Grove system, typically requiring a Grove Base Shield or a board with Grove connectors.
What is the resolution of the accelerometer?
The accelerometer has a 10-bit resolution.
Can I use this sensor with a Raspberry Pi?
Yes, it is compatible with Raspberry Pi when used with a Grove Base HAT or a compatible I2C interface.
What kind of applications is this sensor best suited for?
It is well-suited for hobbyist projects, educational purposes, robotics, basic motion detection, and game controllers.
Does the sensor provide angular velocity or orientation data?
No, this is a 3-axis accelerometer; it measures linear acceleration only. It does not directly provide angular velocity or orientation data, though this can be calculated with additional processing or by combining with other sensors.
Troubleshooting
Sensor not detected or returning zeros
Verify the I2C connection is correct and secure. Ensure the Grove library is properly installed and the correct I2C address is used in your code. Check that the Grove Base Shield is powered.
Inconsistent or erratic readings
Ensure the sensor is not near sources of electromagnetic interference. Check for loose connections. Try running the sensor on a different microcontroller or with a different power supply to rule out external factors.
Incorrect acceleration values
Calibrate the sensor if possible within your application's software. Ensure the sensor is oriented correctly according to its axes (X, Y, Z). Verify that you are using the correct measurement range (±16g) in your code.
Pros and Cons
Pros

Setup, Compatibility & Care
Setup:
- Connect the Grove - 3-Axis Digital Accelerometer to a compatible Grove Base Shield or a board with Grove connectors using the provided cable.
- Connect the Grove Base Shield to your microcontroller (e.g., Arduino, Raspberry Pi).
- Install the necessary Grove library for your microcontroller's IDE. Refer to the Seeed Studio documentation for the specific library.
- Upload the example code provided with the library to read accelerometer data.
Compatibility:
This sensor utilizes the I2C communication protocol. It is compatible with microcontrollers that support I2C, such as Arduino Uno, Arduino Mega, Raspberry Pi, and other platforms within the Seeed Studio Grove ecosystem.
Care:
- Handle the sensor with care to avoid physical damage.
- Keep the sensor away from extreme temperatures, moisture, and direct sunlight.
- Ensure all connections are secure before powering on your system.
- Avoid exposing the sensor to strong magnetic fields, which could interfere with readings.
