Dynamic sensors: measure the acceleration or speed of a movement. They are mounted on the moving element.

• Measurement of speed, acceleration, angle of inclination (acceleration of gravity)
• Gradual analog response, whose intensity depends on the measurement
• Contact sensors

Note: The compass is not dynamic, but is often used in the same circumstances as the inclinometer/accelerometer.

Motion or speed sensors: fixed in a setting or location, they monitor movements within their range.

• Speed measurement, motion detection
• Complexe, analog response
• Contactless sensor
