Motion sensors-accelerometers offer the possibility to measure the acceleration of a body in a given direction. They are used either as standalone sensors or within complex measuring systems. MMA6231Q accelerometer is a three-axis accelerometer, which provides the maximum full scale acceleration of ±2.2g while consuming only 0.25mA/axis. It consumes very little power so it is suitable for battery-driven applications.

MMA6231Q accelerometer has many applications in different fields. It is widely used in control systems, electronic toys systems, human daily activities (running, jogging, pushing, walking etc), gaming systems, vehicle orientation and navigation systems, automatic door systems, automatic lighting systems, automatic control systems, sensor nodes and many more. It can also be used to measure vibration and tilt in various systems.

MMA6231Q accelerometer is based on a resistive mems technology. This technology makes use of a semi-conductor element such as a diaphragm or a beam to sense the acceleration. The diaphragm or a beam is connected to a series of resistors. When the acceleration changes, the resistance of the diaphragm or a beam changes due to the changes in the force acting on it. This change in the resistance is used to measure the acceleration.

MMA6231Q accelerometer has a low power consumption, which makes it suitable for battery powered applications. It has a wide operating range from 0 to 50 degrees Celsius and is capable of measuring acceleration up to 2.2g. It has a small package size of 4.0mm x 4.0mm and is RoHS and WEEE compliant.

The MMA6231Q accelerometer has a digital I2C communication interface, which makes it easy to integrate into a variety of systems. It also has an on-chip temperature sensing circuit which is used to compensate and nullify the temperature related offset drift. The on-chip ADC is used to convert the analog signal from the diaphragm to a digital signal. It has a 14-bit resolution so it is suitable for measuring very small changes in acceleration. The MMA6231Q accelerometer also has a low power mode, which allows it to consume even less power during operation.

The MMA6231Q accelerometer is an ideal solution for many applications where low power and accurate measurement of acceleration in three axes is required. Its low power consumption, small package size and ability to measure acceleration up to 2.2g makes it a versatile and cost-effective solution for a variety of applications.
