Digital Humidity Controller – Electronic Humidity Control Switch (1–99% RH)
Automatically control humidity levels with this digital humidity controller. Designed for humidification and dehumidification applications, it offers accurate RH monitoring, relay output control, and flexible installation for homes, grow rooms, cabinets, and equipment enclosures.
This digital humidity controller is an electronic control instrument designed to regulate humidity levels automatically within a defined range. By switching external humidifiers or dehumidifiers on and off based on real-time readings, it helps maintain stable environmental conditions for comfort, storage, or process control.
The controller supports both humidification and dehumidification modes, with adjustable upper and lower humidity limits and built-in hysteresis to prevent rapid relay cycling. A remote humidity sensor probe ensures accurate measurement, while an additional temperature probe enables temperature compensation for improved humidity accuracy.
Featuring a clear digital display, simple button navigation, and data retention during power loss, this unit is well suited to residential, light commercial, and technical applications where reliable humidity regulation is required.
