UV Angel: UV Angel Clean Air™

The UV Angel team has one primary focus: make the world a cleaner and safer place for everybody. The company uses advanced research and development in ultraviolet light to reduce harmful pathogens in the air and on surfaces. Their patented and safe technologies disinfect harmful viruses, bacteria, and fungus with no harmful chemicals or human interaction. Originally developed for hospitals, this leading technology is now used across the world in healthcare, restaurants, education, athletics, government, and more. UV Angel helps make the environments in which we live, shop, eat, and work measurably safer and cleaner.

Business Challenge:

UV Angel was ready for the next generation of its Clean Air™ Series product.

This modern ceiling-mounted product combines standard in-ceiling lighting with a proprietary UV-C air treatment system. Air is pulled into a sealed UV-C chamber where germs are killed with up to 99.99% effectiveness. The disinfected air is then returned to the room. The company needed to give its customers visibility to real-time statistics, usage, performance, and preventative maintenance metrics on fleets of installed devices. They also wanted to build an infrastructure that would accommodate future use cases. They realized the need for a secure and authenticated Bluetooth Low Energy (BLE) interface and an over-the-air solution for firmware updates.

Approach:

UV Angel partnered with Mutually Human to enhance its product and infrastructure, developing embedded firmware to safely manage and monitor Clean Air™ components.

UV Angel selected Mutually Human, a recognized leader in software consultancy and development, to collaborate with them to provide consulting and technology teams to advance the product and the infrastructure. Embedded firmware was developed to safely run and monitor all of the Clean Air™ components, including configuration & calibration.

Results:

We optimized cloud connectivity and remote monitoring for UV Angel’s Clean Air™ system, enhancing MQTT telemetry, secure firmware boot, BLE-based device control, and mobile app support for seamless configuration, calibration, and maintenance tracking.

Cloud Connectivity & Remote Monitoring

We enabled seamless cloud connectivity using MQTT telemetry, allowing remote configuration, monitoring, and fault detection for improved system performance.

Secure Firmware & Authentication

A secure boot feature was implemented to ensure firmware authenticity and security, preventing unauthorized code execution and enhancing device reliability.

Mobile App Enhancements

Mutually Human updated the existing iOS WiFi provisioning app to support the product, enabling offline calibration and seamless user setup.

Device Command & Control via BLE

A BLE-based control feature was developed, allowing users to monitor UV bulb and filter maintenance needs while managing the system’s real-time state.

Embedded Software Integration

We collaborated with mobile and cloud teams to integrate embedded software with the broader system, ensuring seamless communication across all components.
