Humidity Sensors

Controlling humidity in buildings is critical to occupant comfort. It is also important to protecting building infrastructure, production processes, stored goods and museum artwork. The range of durable room, duct, outdoor air and condensation sensors is designed to provide energy-efficient monitoring and is compatible with all major BACS. High-quality sensors that perform reliably provide high accuracy and repeatability. Combined temperature and humidity sensors provide a flexible and cost-effective solution.

With the expansion of the product range for visible areas of the room, Belimo offers the architect an aesthetic and timeless design, the installer quick installation, the system integrator easy commissioning by a smartphone and the end customer a comfortable room climate.



  • Complementary Metal Oxide Semiconductor (CMOS) based polymer-capacitance sensor with an accuracy of ±2% relative humidity as standard and long-term drift <±0.25% not affected by high humidity and contaminants.
  • Multisensor with selectable output-measurement values: relative humidity, absolute humidity, enthalpy and dew point.
  • Belimo room sensors have an aesthetic, timeless design and offer easy configuration and diagnostics of active devices via NFC.
