MMA5248NDKGWR2 Application Field and Working Principle

Introduction

The MMA5248NDKGWR2 is a high-precision, low power, three-axis acceleration sensor. It can measure acceleration up to 2g and has a wide bandwidth performance not exceeding 5%. It is usually used for motion sensors, pressure sensors, pressure sensors, position sensors and similar applications which require accurate measurements of acceleration. It has a very low power consumption and can be integrated into systems with tight power requirements.

Application Field

MMA5248NDKGWR2 is mainly used in motion sensors, where its low power consumption and high accuracy make it the most suitable solution. It can be used in inertial navigation systems, game controllers, personal navigation devices, optical mouse, vibration and tilt detection, cellular phones, multimedia players and office equipment. It is also widely used in industrial applications, including for medical device and instrumentation, robotics, automotive safety, automotive manufacturing and military and industrial control systems.

Working Principle

The MMA5248NDKGWR2 is an accelerometer sensor which works by detecting variation in acceleration in all three axes. It is based on the principle of change in capacitance. It is constructed on the quartz crystal structure which acts as a resonator oscillator. When there is an acceleration along any axis, the mass inside the sensor moves and shifts the position of the quartz crystal along the axis, resulting in a capacitance variation. The capacitance variation is converted to voltage by a circuit connected to the sensor. Then, the voltage is further processed by a microprocessor to generate the acceleration data.

Conclusion

MMA5248NDKGWR2 is a high-precision, low power consuming three-axis accelerometer sensor which can measure high precision up to 2g and has a wide bandwidth performance not exceeding 5%. It can be used in motion sensors, inertial navigation systems, game controllers, personal navigation devices, optical mouse, vibration and tilt detection, cellular phones, multimedia players and office equipment. The Working Principle of the MMA5248NDKGWR2 is based on the principle of change in capacitance of the quartz crystal oscillator.
