Humidity sensor SPC DucoBox Energy Humidity SensorDUCO for ventilation systems

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.
