MMA5248KWR2 Motion Sensor - Accelerometer

MMA5248KWR2 is a motion sensor and an accelerometer from STMicroelectronics. It is used for motion sensing and vibration measurement applications in various industries such as consumer electronics, medical, automotive, aerospace, and industrial automation. The main application fields of this motion sensor are vibration monitoring, human motion sensing, robotic and machine control. This motion sensor from STMicroelectronics is capable of measuring linear acceleration in a range between -4g and +4g.

The MMA5248KWR2 motion sensor consists of two axes, namely x-axis and y-axis. It is a capacitive MEMS accelerometer which senses motion by measuring the changes in its capacitance. The capacitance of the device is changed as it experiences an acceleration. The MEMS capabilities of the MMA5248KWR2 motion sensor enable it to resist shock and vibration and provide a quick response to acceleration changes. The integration of a temperature compensation circuit allows the device to measure the acceleration accurately without temperature effects.

The motion sensor also comprises two signal-conditioning channels which provide temperature, signal output and current bias. These two channels are used to convert the output signal from the accelerometer to a frequency based output. This frequency based output can be further processed and interfaced with digital systems or microcontrollers. The MAA5248KWR2 motion sensor from STMicroelectronics also comes with an integrated power management circuit and can be operated using a single supply of 2.5V to 5V.

The working principle of MMA5248KWR2 motion sensor is based on the physical principle of capacitors. The capacitive sensing technology works by measuring the capacitance changes in the MEMS capacitors as they experience acceleration. As x- or y-axis of the capacitive sensing cell experiences an acceleration force, its capacitance changes and this varies the output frequency of the device. The output signal from the accelerometer is sent to a signal conditioning circuit which further converts the signal into a digital output. As the sensing cell is subjected to a constant acceleration, the output signal will have a corresponding frequency.

The MMA5248KWR2 motion sensor from STMicroelectronics is a reliable and cost effective solution for motion sensing applications. The MEMS structure enables it to withstand shocks or vibration and offer a quick response to acceleration changes. The integration of a temperature compensation circuit further ensures accuracy in measurements. Moreover, its user-friendly design makes it easy to be interfaced with digital systems and microcontrollers.
