An IoT refrigerator collects sensor data from an Arduino-attached gyroscope to track opening counts, durations, and send the data every minute to a visualization platform. A web application was then developed to aggregate the raw sensor data by day, month or year through a server-side API, and display interactive summaries on the client-side using D3.js.

- 2. Iot Refrigerator • I attached a gyro sensor with Arduino to the refrigerator door. • Collect the sensor data by Sakura Iot Platform.
- 3. Data Contents • Refrigerator open count. • Refrigerator open second. • Send from Arduino every one minutes.
- 5. A new demand arises • Aggregate by day,month,year. • With simple operation.
- 7. Server side API Request { start : 2017 , end : 2018 ,unit: year } Response {[ timestamp : 2017 , open_count :1034, open_second :4123], [ timestamp : 2018 , open_count :983, open_second :5120]}
- 8. Client Side • D3.js - D3.js is a JavaScript library for manipulating documents based on data.
