Hygroregler

Hygroregler is a device or system designed to maintain a target relative humidity within a space or enclosure. It combines a humidity sensor with a control mechanism that activates one or more moisture-adjusting actuators to keep the environmental humidity within a specified range.

Typically, a hyg regler consists of a humidity sensor (and sometimes a temperature sensor), a controller that compares the measured value to user-defined setpoints, and actuators such as a humidifier, dehumidifier, or controlled ventilation. Control strategies may include simple on/off (hysteresis) logic, proportional control, or more advanced methods like PID to reduce fluctuations and improve stability. Some systems offer data logging, remote monitoring, alarms, and integration with building management systems.

Common applications include greenhouses and horticultural facilities, where precise humidity supports plant health and disease control; archival, museum, and library environments where stable RH protects sensitive materials; pharmaceutical and food storage where humidity affects product quality; and data centers and commercial buildings where humidity management contributes to equipment reliability and occupant comfort.

Advantages of using a hygroregler include improved product quality, artifact preservation, energy-efficient humidity control, and the ability to maintain uniform conditions across a space. Limitations can involve sensor drift, installation and calibration requirements, energy consumption by humidity actuators, and the need for proper placement to avoid microclimates or measurement errors. Modern systems increasingly integrate with smart building networks and offer remote access and advanced analytics.
