Web-App-for-Smart-Refrigerator

Web App for Smart Refrigerator, using Intel Edison and AWS service.

Summary

• Determine food category(label) in the refrigerator by image recognition, and update the information on the server and mobile App.
• Maintain a real-time data of food collection in fridge with related information(calorie, weight, expiration date, etc.)
• Track food expiration dates and monitor the internal temperature and humidity of the refrigerator.
• Give users recipe recommendations based on the current food in the refrigerator.

Detailed Description

Sensor node are responsible for

• Detecting the motion of the user
• Capturing the image of the food and the image will be sent to AWS S3
• Weighing every food, then send its weight readings along with the image
• Collecting the temperature and humidity data

AWS is responsible for

• Receiving and keeping the food image(S3)
• Detecting food label(Rekognition and functions in Lambda to derive the most relevant one)
• Analysing the meta data and storing the result into DynamoDB

APP is responsible for

• Displaying the foods in the fridge
• Real-time temperature & humidity and cal. Consumption tracking
• Recommendation for the recipe based on the current food in the fridge
