MMA6821AKW is an innovative motion sensor-accelerometer which is developed by NXP. Weighing only 3.3g, it contains a self-calibrated and transverse-hetero-axis capacitive accelerometer which measures dynamic acceleration or tilt in the three mutually orthogonal directions—X, Y, and Z axis with an accuracy of ±6g. It also has nil-relative cumulative error rates and a wide power supply range of 1.8V to 3.6V.

The MMA6821AKW accelerometer provides a wide range of applications and advantages over other motion sensors. It can be used in automotive safety systems, event detectors, industrial process control systems, as well as gaming, consumer, and medical applications that require dynamic tilt, rotation, or acceleration sensing. This is due to its reduced size, high accuracy, and low cost. It has a minimum system power consumption and an embedded temperature compensation algorithm that offers excellent stability over a wide temperature range.

The MMA6821AKW accelerometer has two sensing elements which measure the change of capacitance due to a mechanical movement in its environment. When the motion or acceleration of the accelerometer changes, the sensing elements sense the motion and vibrate, inducing a signal. The resulting oscillatory signal is then amplified by an amplifier and converted into digital output by an analog-to-digital converter. Those in-built electronics then accurately sense the tilt or motion of the accelerometer and generate a proportional signal of 0–5V at the output.

MMA6821AKW is a fully integrated accelerometer, with a wide operating temperature range, a resolution of up to 4096 LSB/g, a noise level of less than 2mg, and wide bandwidth up to 4kHz. It has a full set of on-chip functional blocks, including amplifier, temperature compensation coefficients (TCO) calculator, embedded controller, and diagnostic module. This accelerometer is also designed with a selectable low-power consumption mode, allowing the device to be used in portable applications. MMA6821AKW is suitable for both industrial and consumer applications.

In summary, MMA6821AKW accelerometer provides an excellent monitoring solution which is perfect for applications such as industrial or consumer applications that require dynamic tilt or acceleration sensing. That’s why it is increasingly being used in automotive safety systems, event detectors, industrial process control systems, gaming, and medical applications. It provides high accuracy and stability over wide temperature range. In addition, it has a wide power supply range of 1.8V to 3.6V and also guarantees low power consumption. It’s no wonder that MMA6821AKW accelerometer is becoming one of the most popular motion sensors on the market.
