MMA7361 PDF Datasheet – Triaxial Acceleration Sensor

This post explains for the sensor. A triaxial acceleration sensor, also known as a 3-axis accelerometer, is a sensor device that measures acceleration in three perpendicular axes: typically, the X, Y, and Z axes. This sensor is designed to detect changes in velocity or acceleration and is commonly used in various applications, including automotive systems, consumer electronics, aerospace, robotics, and industrial equipment.

The Part Number is MMA7361.

The function of this semiconductor is Triaxial Acceleration Sensor.

The package is 3mm x 5mm x 1.0mm LGA-14 Package

Manufacturer: NXP, Freescale, ETC

The MMA7361 is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, 0g-Detect which detects linear freefall, and g-Select which allows for the selection between 2 sensitivities. Zero-g offset and sensitivity are factory set and require no external devices.

The MMA7361LC includes a Sleep Mode that makes it ideal for handheld battery powered electronics. This module can be used for signal disposal、unipolar low-pass filter and temperature compensation technology because it use low-cost micro capacitive accelerometer and four ranges which is optional for user choosing in four of the sensitivity. This device include a low-pass filter and zero g compensation.
