IMU Sensor for In-Situ 3D Movement Monitoring of Particulate Matter

This contribution describes the prototype of a compact IMU sensor with dimensions of 30 mm × 20 mm × 10 mm. The sensor integrates a three-axis gyroscope module, LSM6DSL, along with onboard memory and a processing unit. The device was used to measure linear motion along the X-axis over a distance of 630 mm, giving a measured length of 659 mm. The absolute error was 29 mm, with a relative error of 4.6%. This error was likely attributable to manual movement during the measurement process.
