Industrial convection oven HMI interface
Project
Overview
Android HMI applications developed for three related industrial machines — oven, spiral mixer and proofer — with UART machine control, multi-sensor monitoring, MQTT cloud sync and OTA updates.
Business
Context
Central kitchens and industrial bakeries need consistent recipe distribution, live machine telemetry and serviceable operator interfaces across related equipment.
Challenge
Support distinct machine types with shared industrial Android platform patterns while exposing sensors, recipes, manuals and remote control safely.
Solution
Separate Android HMI apps per machine on a common industrial board stack, with MQTT cloud sync, local/cloud manuals and OTA firmware/app updates.
