Sensor categories
IMUs & Motion Units
- MPU6050 6-axis IMU
- 9-axis IMUs (gyro + accel + mag)
- Orientation & motion fusion
Position & Rotation
- Rotary encoders
- Potentiometer angle sensors
- Hall-effect position sensors
Speed, Tilt & Vibration

Tip: For precise angle control, use IMUs with sensor fusion (Kalman/Madgwick) rather than raw accelerometer or gyro readings.
Motion sensor chooser (quick guide)
| Need | Best choice | Notes |
|---|---|---|
| Track angle or tilt | Accelerometer or IMU | IMUs give smoother, fused readings. |
| Measure rotation / knob position | Rotary encoder | Use for motors, knobs, CNC & robotics. |
| Detect simple tilt movement | Tilt switch | Great for alarms, triggers, orientation sensing. |
| Measure vibration or shock | Vibration sensor | Use for machinery monitoring or touch activation. |
| Track speed/RPM | Hall-effect speed sensor | Use for wheels, motors & automation. |
| Full motion tracking | 6-axis / 9-axis IMU | Used in drones, robots, VR & stabilization. |
Accuracy depends on sampling rate, filtering, and calibration.

FAQ
Are IMUs hard to use?
No—libraries exist for MPU6050, MPU9250, LSM6, and others. Sensor fusion improves accuracy.
Which sensor is best for robot navigation?
Use a 6-axis or 9-axis IMU with encoders for precise odometry and movement control.
Do rotary encoders need debouncing?
Mechanical encoders may need software filtering; optical/magnetic encoders do not.
Do you ship nationwide?
Yes—fast PH shipping with same-day processing for in-stock items.
