It consists of PXLS82722AESR2 Acceleration Sensor, Temperature Sensor, Signal Conditioning, Analog, and Digital Circuits. With excellent performance and low power consumption, it is widely used in application fields such as consumer mobile, vehicular vibration sensing, and industrial control systems.

In the consumer mobile field, PXLS82722AESR2 can sense motion of cellphone very accurately, including drop detection, user activity sensing, 3D game controlling, and imaging stability. It is also capable to measure in many kinds of industrial equipment such as motors, pumps, generators, etc. With PXLS82722AESR2 embedded, the equipment can respond to acceleration, vibration, and shocks in real time, providing an accurate description of the overall working conditions of the machine.

Working Principle

PXLS82722AESR2 Accelerometer detects motion using a set of MEMS (micro electro mechanical systems) detectors and processes the data using highly sophisticated algorithms. It measures acceleration along the three primary axes (X, Y, and Z) of the device, transferring the motion of the device through an external connection. The output is filtered by a digital and analog filter to obtain a smooth and accurate signal.

The motion is measured by PXLS82722AESR2 with a combination of accelerometers and gyroscopes. According to Newton\'s second law of motion, the accelerometer measures the device’s linear acceleration, which is the rate of change in velocity of the device. The gyroscope output is then used to measure the angular acceleration of the device, which is the rate of change in angular velocity. With the combination of these two measurements, the PXLS82722AESR2 can detect and measure the motion of the device with extreme accuracy.

In addition, PXLS82722AESR2 accelerometer applies adaptive temperature compensation to improve the accuracy and stability of motion sensing and to reduce the capacitor tolerance requirement on power supply. As a result, it delivers superior motion accuracy in high temperature environments and over a wide range of capacitance variations.

Conclusion

PXLS82722AESR2 is a high performance, low power, three-axis linear accelerometer and it can be widely used in consumer mobile, vehicular vibration sensing, and industrial control applications. It combines accelerometers and gyroscopes to provide accurate and reliable motion sensing data. The adaptive temperature compensation makes it more accurate and stable in high temperature environments.
