This repository complements the Master's thesis titled "Development of a Low-Cost Ultrasound Flow Sensor". The objective of this work is to develop a sensor based on the ultrasonic transit-time technique to determine the flow rate and composition of biogas, and to evaluate its performance.
The sensor uses a combination of the TDC7200 and TDC1000 integrated circuits to measure the ultrasonic time of flight in both flow directions, enabling flow velocity estimation.
The repository is organized according to the following structure. Each folder contains a README.md file describing its contents:
ultrasonic_flowsensor/
├── CAD/ # Mechanical design of the sensor housing
├── PCB/ # Schematics and PCB layout files
├── Firmware/ # Embedded firmware for signal generation and processing
Renderings of the final iteration of PCB and housing desing are provided here:
