The document discusses an IoT refrigerator project that collects sensor data on refrigerator door openings using an Arduino and gyro sensor. The data includes open count, open seconds, and is sent every minute to an IoT platform and visualized on a graph. A web application was then developed to aggregate the raw data by day, month, or year in response to API requests. The client side uses D3.js to visualize the aggregated data.
