In this project, I built a portable speed trap that can be used to monitor traffic speed conditions in your neighborhood. By using an ML model to identify vehicles, a doppler radar sensor to detect speed, and a cellular module to relay collected data to the cloud, it was surprisingly easy to build out this IoT solution!
