Weight-aware tracking
Load-cell sensors are intended to measure the weight on each assigned bottle platform, helping estimate the remaining spice quantity.
Introducing The Rack
Less searching.
More seasoning.
A smart kitchen organizer concept that brings your spice shelf and your digital inventory a little closer together.
✓ Weight-aware inventory✓ Refill-level reminders✓ Digital shopping list
Everything in its placeA considered home for your spices
Designed around everyday cooking
A smarter shelf,
without the fuss.
The Rack brings practical storage together with the idea of knowing what you have and what needs topping up.
Refill status at a glance
A companion app concept shows stock levels and uses your chosen thresholds to flag spices that need attention.
A more useful shopping list
Keep track of the spices you need to replenish and make your next grocery trip more intentional.
The idea in three steps
Simple on the shelf.
Helpful on your phone.
The planned experience connects physical weighing platforms to a digital inventory, so the useful information is easy to find when you need it.
Place your spice
Each bottle sits on its assigned weighing platform in the organizer.
Measure and sync
The sensor reading is handled by the ESP32 and intended to sync with the companion app through Wi-Fi and Firebase.
Know what needs a refill
See quantities, monitor your chosen minimum levels, and plan what to add to your shopping list.
A few useful details
Good questions.
Clear answers.
The Rack is being developed as a project concept. These notes explain the intended approach.
Does The Rack use NFC or indicator LEDs?
No. The current project plan focuses on weight measurement, digital inventory, stock thresholds, refill alerts, and shopping-list management. NFC and LED features have been removed.
How will the spice quantity be estimated?
A load cell and HX711 amplifier measure the load. The software will use calibration and the bottle's tare information to estimate spice quantity in grams.
Will the app show live updates?
The intended architecture is ESP32 → Wi-Fi → Firebase → Android app. Real-time updates depend on completing and testing that hardware and cloud integration.
