In the NAU7802 Food Scale Learn Guide, you can build a food scale using CircuitPython, a NAU7802 STEMMA board and a strain gauge. In this guide, you'll take that project and connect it to Microsoft Azure to log the weight measurements over time. Additionally, you'll setup a text alert when it looks like you need to refill the food container.
Tracking inventory usage over time is a great way to utilize IoT tools. It can help you see patterns and better plan for the future. In the context of pet food, it can also help you monitor your pet's diet.
Prerequisite Guides
- The Getting Started with Microsoft Azure and CircuitPython Learn Guide goes through everything you need to get up and running with Microsoft Azure and CircuitPython.
