ADXL335
The ADXL335 is a small, low-power, 3-axis accelerometer that is widely used for detecting tilt, motion, and acceleration in various embedded applications. Unlike the MPU6050, which includes both an accelerometer and gyroscope, the ADXL335 is purely an accelerometer, making it simpler and often more suitable for low-power and basic motion-sensing applications.
