From the project
Developed a cost-effective telematics device for automobiles, capable of enabling user-based insurance models to save up to 30% on premiums. Features include a two-layer PCB design in KiCad, efficient firmware in C with CMake, and advanced noise reduction in IMU sensors using Python.
1) The project involved the use of AECQ100 grade IMU and Temperature and Humidity sensors (SHT30A) sensors for which custom breakout boards had to be created in KiCAD and hold soldered: #### Breakout Board PCB of AEC-Q100 compliant SHT-30A Temperature and Humidity Sensor #### Breakout Board PCB of AEC-Q100 compliant 6-DOF IMU ASM330LHHXTR #### Fabricated Breakout Boards with IC
