1. What is MPU‑6509

MPU‑6509 is a 6‑Axis MEMS Inertial Sensor (IMU) manufactured by TDK‑InvenSense.It integrates a 3‑axis accelerometer and a 3‑axis gyroscope. No extra external chips are required. A single chip can detect tilt, rotation, movement and attitude.Compact 3×3 mm LGA surface‑mount package, widely adopted in electronic products.

2. Core Functions

‑ Detect object tilt and tilt angle‑ Measure object rotation and rotational speed‑ Sense shake, vibration, drop and locomotion‑ Output attitude angles via sensor fusion algorithm for main‑board intelligent control

In short: It enables machines to know their current orientation and motion status.
