From the project
6-Axis IMU + Qvar Sensing Node with Edge AI capabilities. Specialized for high-accuracy motion tracking and charge-variation detection in modular embedded systems.
Designed as a core component of my Modular Instrumentation Ecosystem, this board integrates seamlessly with my USB-PD Power Hub for filtered power and the STM32H7S3 System-on-Module for high-speed digital signal processing and edge computing.
1. Leak Detection: In oceanographic or sealed industrial housings, Qvar can detect the presence of moisture or liquid ingress long before it reaches critical electronics. 2. HMI Intelligence: Distinguishes between physical device movement (IMU) and intentional human touch or proximity (Qvar). 3. Vibration Analysis: Utilizing the MLC to categorize…
