Hospital Disinfection HMI & Control Platform
A smart HMI-based control platform for hospital disinfection systems, featuring programmable treatment cycles, room configuration, maintenance management, and production-ready embedded electronics for healthcare environments.
Project Overview
The Hospital Disinfection System HMI & Control Platform was developed for SafeHearth as the intelligent control interface for an automated hospital disinfection device used in healthcare facilities.
The system enables medical staff to configure treatment parameters including room size, operating time, spray intensity, oscillation mode, and treatment profiles through an intuitive Human Machine Interface (HMI).
Beyond machine control, the platform stores room information, maintenance records, serial numbers, and operating history, simplifying equipment management across hospitals and healthcare facilities.
Metanoia was responsible for developing the HMI software, embedded electronics integration, manufacturing, testing, and production of the control units.
Multiple production batches were successfully manufactured, tested, and delivered for deployment.
