Personal Data Acquisition Prototype

PCB
Spring 2025

Black Box that mounts onto vechicles and collects real time sensor data that is uploaded to an online SQLite Database. The system contains 6 sensors including the linear potentiometer, string potentiometer, force transducer, GPS, accelerometer and Yaw rate. All sensor collect data at over 100 hertz and in real-time and the data is archived in the online database that the user can view. Sensors are integrated on PCBs that are controlled by microcontrollers (I2C communication standard) these microcontrollers then transmit the sensor data to a USB hub which combines all data streams onto one USB (USB to UART communication standard). The user plugs the USB into their device, they run the script, and they can view all the sensors acquiring the data. The most notable accomplishment and challenge is synchronizing our sensors and getting all of them to 100 Hz. This included a lot of optimization and synthesis time into order to combine our sensors into one cohesive system. This also demonstrated our great teamwork abillity among the engineers. The most notable area for improvement is to further integrate our sensors into one microcontroller and one PCB thus significantly reducing the hardware and cost of our system.
