In the field of biomedical research, maintaining a clean, stable, and controlled environment for SPF (Specific Pathogen-Free) laboratory animals is critical. This application showcases how the ARMxy edge controller, combined with OpenPLC and Y-series I/O modules, ensures precise environmental control for animal research facilities.
A biomedical laboratory operating a 50-cage SPF-grade animal facility requires continuous monitoring and intelligent control of indoor environmental factors such as ammonia concentration, CO₂ levels, temperature, humidity, and air exchange rates.
ARMxy Edge Controller – Core processing unit running OpenPLC
Y-AI Module – Collects analog signals from environmental sensors
X-DO Module – Controls air handling systems and UV disinfection equipment
The Y-AI module captures real-time environmental data, including:
NH₃ levels via electrochemical sensors (0–20mA output)
Differential air pressure in ducts using pressure transmitters (0–5V)
OpenPLC logic dynamically adjusts the ventilation system to maintain 12–15 air changes per hour, based on the number of animals present.
The system also executes a scheduled UV disinfection routine, activating the disinfection lamps at predefined intervals.
Data is recorded automatically to generate daily environmental reports that comply with industry standards.
✅ Remote monitoring of lab conditions via secure network access
✅ Automatic calibration support for all connected Y-series AI sensors
✅ Energy-efficient operation with adaptive ventilation control
✅ Enhances animal welfare and supports compliance with regulatory standards
This OpenPLC-based solution demonstrates the reliability and flexibility of the ARMxy platform in mission-critical environments. Whether for pharmaceutical labs, research institutions, or clinical testing facilities, ARMxy helps ensure environmental stability, biosecurity, and operational efficiency.
