## Summary description

SPC DucoBox Energy Humidity SensorDUCO is a humidity sensor designed for integration with ventilation and air-handling units. It measures relative humidity to enable demand-controlled ventilation, helping regulate airflow based on indoor moisture levels. Suitable for residential and commercial installations where automatic humidity-based control improves indoor air quality and energy efficiency.

## Long description

SPC DucoBox Energy Humidity SensorDUCO is a compact humidity sensor intended for integration with ventilation and air-handling units. It measures relative humidity in indoor spaces and provides a signal to demand-controlled ventilation systems, enabling automatic adjustment of airflow according to moisture levels. The sensor is designed for use in residential and light commercial installations where balancing indoor air quality and energy consumption is required.
Advantages
The sensor offers accurate relative humidity measurement that supports efficient demand-controlled ventilation. Its compact design allows straightforward integration into existing ventilation systems without taking up significant space. By enabling ventilation to react to actual indoor humidity, the device helps reduce unnecessary fan operation and contributes to more stable indoor conditions. The product is compatible with common control systems used in ventilation setups and is suitable for continuous monitoring.
Suitable for
Residential ventilation systems requiring humidity-based control
Small commercial or office spaces with demand-controlled airflow
Bathrooms, kitchens, and utility rooms where moisture levels vary
Integration with air-handling units for improved indoor air quality
Key specifications
Measurement parameter: relative humidity (RH)
Output type: control signal compatible with demand-controlled ventilation systems
Mounting: designed for integration into ventilation ducts or housings
Operating environment: indoor use in residential and commercial buildings
Design: compact form factor for unobtrusive installation
How to use
Install the humidity sensor in a representative location within the ventilation duct or room where humidity levels reflect typical conditions. Connect the sensor output to the ventilation control unit according to the system wiring diagram and the control unit's input requirements. After electrical connection, verify correct sensor operation by observing changes in ventilation response as relative humidity varies. Calibration or configuration steps, if required, should follow the ventilation system manufacturer's instructions.
Usage recommendations
Place the sensor away from direct moisture sources such as shower heads or cooking surfaces to avoid localized readings. For reliable operation, follow the ventilation system maker's guidance on wiring and control settings, and perform periodic checks to confirm sensor responsiveness. Use the sensor as part of a demand-controlled ventilation strategy to balance indoor air quality and energy efficiency.
