STEVAL-MKI047V1 is a evaluation board with an integrated MEMS sensor meant for capturing motion and environmental data in applications like fitness, health and lifestyle monitoring or consumer and industrial markets. This board is meant to use data-capture products such as accelerometers, gyroscopes, barometers and geomagnetic sensors. It is manufactured by STMicroelectronics and its main features are that it has a non-linearity correction, an embedded ASM330LHH MEMS sensor for the rotation and inclination measurements, low-power sensor interfaces (LPS), digital output and a power management system. When using STEVAL-MKI047V1 in a specific application, the first step is to get acquainted with the hardware. This includes the particular features and functions provided by the board. Most of these features are provided by the integrated MEMS sensor; specifically, the non-linearity correction, the embedded ASM330LHH, the low power sensor interfaces, the digital output and the power management system. Once the hardware is known, it is important to understand the working principle of STEVAL-MKI047V1. This is done by examining the data capture products it utilizes, such as accelerometers, gyroscopes, barometers and geomagnetic sensors. The data capture products measure angular or linear data, from which the board’s motion tracking hardware can translate into meaningful motion. Specifically, the board uses accelerometers and gyroscopes to measure linear acceleration and rotation, respectively. These measurements are then combined to track changes in movement, as well as changes in the surrounding environment.The low power sensor interface used by the board is made up of two components: the main sensor microcontroller and the internal digital interface. The main microcontroller is responsible for taking readings from the accelerometers, gyroscopes, barometers and geomagnetic sensors. The internal digital interface is used to communicate with the microcontroller and transmit data to an external device. The power management system used by STEVAL-MKI047V1 is also an important part of its functionality. This system is responsible for regulating the power supply of the board, ensuring that power is only consumed when needed. The power management system can also be used to monitor battery life and enable energy-saving features on the board.Finally, the non-linearity correction is an important feature on the board. This feature helps ensure that the data being acquired is accurate and consistent. The board also has a digital output which is used to interface with other devices for further processing or display. In conclusion, STEVAL-MKI047V1 is an evaluation board that is meant to capture motion and environmental data in applications such as fitness, health and lifestyle monitoring or consumer and industrial markets. Its working principle consists of the integrated MEMS sensor which consists of the non-linearity correction, embedded ASM330LHH MEMS sensor, low power sensor interface, digital output and power management system. By understanding the features and functions of the board, one is able to confidently use the STEVAL-MKI047V1 to capture accurate and consistent motion data for various applications.
