Precision machinery and electronic components are very susceptible to condensation caused by temperature differences and humidity fluctuations. Condensation within logistics warehouses can lead to quality defects such as corrosion, short circuits, and performance degradation. These issues are difficult to assess visually and may result in problems after shipment and a decline in trust. Since condensation can occur suddenly, it is challenging to prevent it solely through air conditioning management. By continuously monitoring temperature, humidity, and dew point, we can visualize the risk of condensation, enabling proactive measures that stabilize quality and reduce costs. Condensation monitoring is an essential preventive management strategy to protect valuable products and maintain trust. ■ Effects of "visualizing" condensation risk - Detect risks before condensation occurs, allowing for early intervention. - Manage storage environments with numerical data to consistently maintain quality standards. - Strengthen customer and audit responses by ensuring traceability. - Reduce quality costs through defect reduction. ■ Transitioning to "preventive management" to protect quality In logistics warehouses for precision machinery and electronic components, condensation measures require "preventive management" rather than "reactive responses." Our system predicts condensation risk up to 72 hours in advance based on weather forecasts from the Meteorological Agency, supporting preventive management.
