Industrial Smart Cooker HMI recipe grid with multi-cooker status
Project
Overview
An Android-based HMI application for industrial smart cookers, engineered on a customized Android 10 AOSP board with UART control of cooker PCBs and MQTT/cloud synchronisation for recipes and monitoring.
Business
Context
Industrial food-equipment programmes need operator interfaces that control heating cycles precisely while staying connected for recipes, alerts and remote updates.
Challenge
Coordinate multiple cookers from one HMI, bridge serial machine control with cloud recipe workflows, and keep the system serviceable in industrial environments.
Solution
Custom Android HMI with real-time UART control, MQTT data sync, cloud recipe portal integration and monitoring instrumentation.
