Inside a modern automotive paint booth, the control unit continuously analyzes sensor data to keep the work area free of toxic vapors while robotic spray guns operate at high speed. The embedded software orchestrates this process: it gathers readings from gas detectors, compares them with safety thresholds, and instantly commands local exhaust fans to increase airflow or activates audible and visual alarms when limits are exceeded. By logging each event and providing a touchscreen interface, it allows line supervisors to verify compliance, adjust ventilation set‑points, and trace any incident back to a specific shift or equipment segment. This capability enables continuous, unattended operation of paint lines, reducing downtime caused by manual safety checks and supporting the high‑throughput demands of vehicle body production. In a closely related application, the same software framework is employed on battery‑module assembly stations, where it monitors oxygen and hydrogen levels during cell welding, ensuring a safe environment for the growing electric‑vehicle market.
