Measure Extreme G-Forces Up to ±200g — ADXL375 High-G Accelerometer

The Adafruit ADXL375 High-G Accelerometer (STEMMA QT / Qwiic) measures acceleration up to an extreme ±200g — far beyond what standard accelerometers can handle. It's purpose-built for high-impact events like rocket launches, crash testing, projectile monitoring, vibration analysis on heavy machinery, and sports impact measurement.

Unlike typical accelerometers that max out at ±16g or ±24g, the ADXL375 is specifically designed for shock and impact detection where forces are brief but intense. Communication is via I2C or SPI, and the onboard STEMMA QT connectors allow solderless hookup.

Frequently Asked Questions

Is ±200g accurate for small movements? No — this sensor is optimized for high-G events. For subtle motion and tilt, use an MPU6050 or MMA7361 with lower range and finer resolution.
Can I daisy-chain STEMMA QT sensors? Yes. The dual STEMMA QT connectors let you chain multiple I2C sensors on one bus.
