For lab environments, control systems are more than operational interfaces. They help ensure precision, safety and responsiveness across complex ventilation and containment setups.
A global Fortune 500 leader in IoT-driven environmental control systems relied on a portfolio of fume-hood controllers to manage and monitor critical lab environments, ranging from large rooms and ventilation zones to individual fume-hood chambers. One of these products still ran on a legacy 3-inch display that had reached end of life, even as demand for next-generation, IoT-enabled lab equipment accelerated.
With a sister product already running on advanced Android hardware, the client saw an opportunity: modernize the platform and the user experience without absorbing the cost of new hardware.
Legacy Displays and Fragmented UI Logic Limited Product Scalability
Over time, the controller portfolio’s user interface struggled to keep pace with the business. The constraints clustered into four themes:
- Aging platform at end of life: The 3-inch display hardware and its tightly coupled UI could no longer support modern, IoT-enabled experiences.
- Fragmented, low-reuse codebase: UI logic was duplicated across 250+ screens with little standardization, slowing prototyping and feature development.
- Complex IoT integration: Legacy controller integration was complex and not documented anywhere, making behavior hard to understand.
- Heavy testing and maintenance load: The absence of a clean architecture drove high validation effort and made scaling and long-term maintenance difficult.
Together, these constraints made it difficult to deliver a consistent, future-ready experience—especially as demand for next-generation lab equipment increased.
Shaping a Customer-Led Vision into a Reuse-Led IoT UI Modernization Strategy
Rather than treating this as a hardware refresh, the client reframed it as a platform opportunity, re-hosting the experience on its existing next-generation Android foundation and rebuilding the UI on a standardized, scalable foundation. Persistent partnered with the client to design a modern, reuse-led modernization strategy aligned to both immediate operational needs and long-term product growth.
The engagement was structured to maximize reuse of proven assets like codebase, workflows and test plans, so the client could move faster and with lower risk, while establishing an architecture flexible enough to support future product variants.
Scalable Android-Based UI Foundation Standardized 250+ Control Screens
Persistent delivered the modernization through a structured, phased program. The solution included:
- Hardware-neutral migration to a next-generation Android touchscreen display (Qualcomm APQ8009), reusing existing hardware to avoid redesign costs.
- A Flutter-based architecture with a reusable widget library used across 100+ occurrences to standardize and modernize the experience over 250+ screens.
- Clean Architecture introducing clear modularity and separation of concerns for easier maintenance and scalability.
- A modular communication layer that simplified the maintenance of IoT controller integration.
- Reuse of an existing UI codebase, workflows and test assets to accelerate software porting while preserving functionality and reliability.
- A milestone-driven delivery model: structured execution across Learning & Design, Development, Functional Testing, Verification Testing, Integration and UAT—covering Phase I for device UI modernization and Phase II for the Setup Wizard.
Reusable Architecture Reduced Development Effort, Testing Load and Hardware Cost
The transformation delivered measurable impact across development, quality and the product experience:
- Reduced UI development effort by ~30% through reusable components, standardized workflows and a Flutter-based architecture that minimized duplicated work across 250+ screens.
- Lowered testing and validation effort by 15–20% by reusing proven test assets and simplifying the architecture for more predictable verification cycles.
- Faster, more predictable delivery driven by asset reuse and milestone-based governance, with faster team onboarding.
- Improved maintainability and scalability through Clean Architecture, ready to support future product variants.
- More reliable IoT controller integration via the modular communication layer, reducing financial and delivery risk.
Future-Ready IoT Platform for Scalable Lab Safety Innovation
By modernizing on existing hardware, the client now has a future-ready, maintainable platform positioned to support new product variants and deeper IoT integration with confidence, directly resolving the end-of-life and fragmentation constraints that prompted the engagement.
The engagement demonstrates how enterprise IoT and building-automation organizations can unlock long-term value through platform-led modernization, accelerating their roadmap without the cost and disruption of a hardware refresh.
