Spot On is an implementation of an intelligent parking sensor system powered by image recognition. The key components of Spot On are MAX78000 microcontrollers to facilitate the detection of whether parking space are available or not. The MAX78000 provides Convolutional Neural Network acceleration, which allows a custom ML image recognition model to run in near real time. The system uses LoRa transceivers integrated into each sensor module, and a central gateway will receive and save the data into a database. Available parking spaces are displayed via an Android app to allow users to locate free parking spots quickly and efficiently.
