This article describes work related to embedded motion data logging, focusing on inertial sensing, data acquisition, and wireless data access.
The system is based on an ESP32-S3 microcontroller, selected for its processing capabilities and integrated Wi-Fi. The device operates as a standalone data logger while allowing wireless configuration and data retrieval.
An onboard IMU is used to measure acceleration and angular rate. Sensor data is sampled continuously, timestamped, and organized to capture motion dynamics such as vibrations, orientation changes, and transient events.
Data storage is handled through two complementary mechanisms:
- Wireless data transfer over Wi-Fi for quick access and configuration
- Local storage on microSD, enabling long-duration recording without network availability
This dual approach improves reliability during extended data collection sessions.
Overall, the work focuses on combining inertial sensing, embedded data logging, and wireless connectivity to support motion analysis in real operating conditions.
