The EDWIES is a WiFi-enabled temperature and humidity data logger designed for indoor environmental monitoring. It measures ambient conditions within a range of –20 to 70°C and 0 to 99% RH, making it suitable for offices, storage rooms, and residential spaces. A key feature is its mold risk indicator, which helps facility managers and inspectors identify conditions that could encourage mold growth before problems occur. The device includes an E‑Ink display for local verification and audible/visual alarms to alert users when thresholds are exceeded. Data is transmitted to LoggerFlex Cloud, where it can be accessed remotely for centralized oversight and compliance reporting. Applications include housing inspections, preventive maintenance programs, and monitoring sensitive environments such as museums or archives where humidity control is essential. By combining reliable logging with proactive risk assessment, the EDWIES supports both occupant well-being and preservation of materials.
