Applications

• Climate control: regulation of heating, ventilation and air conditioning systems according to room temperature and humidity levels to maintain a comfortable indoor climate.

• Prevention of mold and moisture damage: monitoring humidity levels to prevent mold and fungal growth in basements, bathrooms and other damp areas; the sensor can trigger ventilation or drying equipment as needed.

• Alerts and notifications: notifications or alarms when temperature or humidity exceed previously set thresholds – helps prevent, for example, pipe freezing in winter or excessive humidity.

• Optimization of greenhouse conditions: maintaining a microclimate suitable for plant cultivation by regulating humidity and ventilation based on temperature and humidity levels.

• Enhanced security: detection of unusual temperature changes that may indicate fire or water damage.

• Home appliance control: control of dehumidifiers, humidifiers and fans based on humidity and temperature conditions.
