When desiging IoT and wearable devices, having reliable and accurate sensor data is crucial. However, testing and validating multiple sensor types can be a cumbersome and time-consuming task. That's where the STEVAL-MKI120V1 sensor evaluation board comes in. In this blog post, we'll be taking a closer look at this powerful tool and exploring its features and capabilities.

Overview of the STEVAL-MKI120V1

The STEVAL-MKI120V1 is an evaluation board that allows you to test and evaluate a wide range of sensors, including accelerometers, gyroscopes, magnetometers, pressure sensors, and more. The board is designed to work with STM32 microcontrollers, but can also be used with other platforms. It supports popular communication protocols such as I2C, SPI, and UART, making it easy to integrate with different systems.

One of the key advantages of the STEVAL-MKI120V1 is its versatility. It comes with multiple sockets that support a range of sensor modules, so you can easily swap them out and test different sensors without needing to redesign your board. Additionally, the board features an STM32 microcontroller that can handle signal processing, filtering, and data logging, giving you more flexibility in how you use the data generated by the sensors.

Using the STEVAL-MKI120V1

Getting started with the STEVAL-MKI120V1 is easy, thanks to its intuitive software interface. STMicroelectronics provides a comprehensive software library that includes drivers, examples, and documentation to help you get up and running quickly. You can use the software to configure the board, read sensor data, and visualize the data in real-time.

One of the key features of the STEVAL-MKI120V1 is its ability to perform sensor fusion. This involves combining data from different sensors to improve accuracy and eliminate noise. For example, by combining data from an accelerometer and a gyroscope, you can determine the orientation of the sensor more accurately than using either sensor alone. The STEVAL-MKI120V1 can handle sensor fusion using popular algorithms such as Kalman filtering or complementary filtering.

Another useful feature of the STEVAL-MKI120V1 is its ability to log data to an SD card. This means you can collect sensor data over extended periods of time and then analyze it offline. The board also includes LEDs and a buzzer that can be used to indicate sensor events or status, making it easier to debug and visualize the sensor data.

Applications of the STEVAL-MKI120V1

The STEVAL-MKI120V1 is a versatile evaluation board that can be used in a wide range of applications. Here are a few examples:

Wearables: The board can be used to test and evaluate sensors for fitness trackers, smart watches, and other wearable devices. By combining data from multiple sensors, you can accurately track movements, monitor heart rate, and more.

Industrial control: The board can be used to test sensors for industrial control applications, such as vibration monitoring, temperature sensing, and fluid level sensing. The ability to perform sensor fusion and log data makes it easier to identify patterns and diagnose issues.

Robotics: The STEVAL-MKI120V1 can be used to test sensors for robotic applications, such as navigation, object detection, and obstacle avoidance. The ability to perform real-time sensor fusion and process large amounts of data makes it invaluable for robotics research and development.
