I'm working on a DIY Arduino-based project aimed at helping diabetics track their meals and glucose levels more easily. The idea is to use an RFID scanner to log meals, and sync with a basic glucose tracking module or manual input via buttons.
The user would scan a meal tag (e.g., “grits,” “oatmeal,” etc.) and the system would record the time + optional sugar value. Later, you can analyze how different foods affect levels.
I’m curious if anyone here has worked with similar food-diet logging projects using Arduino?
I’m also looking into the nutritional effects of specific foods — for example, — and plan to customize alerts based on food type.
Any suggestions for data logging options (SD card vs online logging)?
Where will be the database and what will it run on. How many types of oatmeal are there? You could probably scan the product RFID tag, already on the package.
Sounds simple, but there is a lot of nuance, especially in the USA, as most food is adulterated, unlike in Europe. You need to spend a significant amount of time writing a requirements document in sufficient detail to proceed. Ensure that you specify where you will obtain the nutrition data from and how it is related to the actual food. Think online, think BIG database. I think it can be done, but it is almost guaranteed to be too much for anyone without significant professional experience. I am not saying a patient, enthusiastic amateur can't get close, but it will challenge you.
Really? We use bar codes here for everything groceries, but I wish they would transfer to QR instead. The bar codes are already printed on the package, are RFID tags also attached from factory?
The problem is that unless you have special UHF RFID tags you can only read one tag. If you have more than one in the field then they will interfere with each other and you will read none of them.
So do you know what sort of RFID tags are in your boxes?
