Motion sensors, such as accelerometers, are a type of device used to measure the acceleration and orientation of a physical body. The MMA5206NPKGWR2 is a low graphic accelerometer from Freescale, designed to measure acceleration on up to three orthogonal axes.

The sensor\'s package is a flex surface mount (SMD). It can detect a great range of accelerations with a sensitivity level ranging from 14-bit to 12-bit. The MMA5206NPKGWR2 also offers a built-in interrupt to facilitate the detection of motion and a gyroscope for additional features.

The MMA5206NPKGWR2 integrates a 2.4V+2.8V+3.3Voperating voltage, a configurable band gap voltage reference, an accelerometer interface, a temperature sensor, a 12-bit ADC, and a 3.3V LDO regulator. Its operating temperature ranges from −40°C to +105°C.

The MMA5206NPKGWR2 accelerometer is appropriate for a variety of applications in areas ranging from industrial and electronics, consumer, aerospace, automotive, and more. Typical applications include tilt-sensing, motion detection and gesture recognition.

The principle of operation is based on the fact that an accelerometer measures linear acceleration, using a measuring device, such as a capacitor. The MEMS accelerometer works in such a way that when the device is put into motion, the proof mass is deflected due to the inertia current. The resulting capacitance change causes the output voltage to change, which is then measured by the accelerometer. The accelerometer then outputs a voltage that is proportional to the linear acceleration.

In summary, the MMA5206NPKGWR2 is a low-g accelerometer used to measure acceleration in three orthogonal axes, making it suitable for a variety of motion sensing applications. It features a high sensitivity level, a low noise level and a wide operating temperature range. The accelerometer operates on the basis of measuring a capacitance change caused by a proof mass deflection, resulting in a proportional voltage change.
