DRS Enabled Smart Pantry
Most of the times, when we want to cook something, we find that some cooking ingredient (onion, garlic, chili etc.) is running low. In some cases, we buy wrong item such as garlic instead of onion.
To get rid from such situation we built a Smart Pantry which can order automatically to replenish every ingredients of pantry with Amazon DRS. Busy life, easy solution!!!
We used Force Sensitive Resistor (FSR) to detect the absence of ingredient in a specific box of the pantry. Arduino UNO is used to read the sensor value.
For sensing the shortage of ingredients in a box to measuring weight of each box with force sensitive resistor. we placed one fsr below each compartment and tried to put it at the center of the compartment. Using mini drill we made two holes for every sensor to bring out the pin of the sensor out of the box. Then I soldered jumper wire to each pin of the sensors to connect it with Arduino. Three sensors will be used for three separate parts of the box and sensors will be placed in the center of each box.
DRS provides connected devices with direct access to Amazon’s powerful retail platform to order any item automatically. With easy-to-use APIs, device manufacturers can take advantage of Amazon's authentication and payment service.
After integrating with Amazon services like Login with Amazon (LWA) and Simple Notification Service (SNS), a simple API call allows a manufacturer to place a product order on behalf of a customer.
. A mobile and web app will be develop for the user to manage the inventry.

This device will enable user to maintain kitchen items with less intervention. Amazon Simple Notification Service (Amazon SNS) is a fast, flexible, fully managed push notification service that lets you send individual messages or to fan-out messages to large numbers of recipients. Amazon SNS makes it simple and cost effective to send push notifications to mobile device users, email recipients or even send messages to other distributed services. Additionally, Mobile and web app will allow user to maintain and monitor each and every thing related to kitchen
