Room Sensors | Temperature, RH, Dew Point, Light and Motion Detection

The Foundation of Comfort

Belimo room sensors accurately measure temperature, humidity, and CO2 in a surface-mounted streamlined design with or without an ePaper touch display. The sensors are maintenance-free and provide long-term reliability for a comfortable room environment. Integrated with Near Field Communication (NFC), the room sensors can be quickly and easily set up or adjusted using the Belimo Assistant App and a smartphone. The App for non-display and touch display versions allows easy data access, field adjustability, commissioning, and troubleshooting even without power.

Belimo room sensors' touch display can be displayed or hidden via the App. The App or the touch display allows easy data access, field adjustability commissioning, and troubleshooting. For devices without an integral ePaper display, setpoints can be programmed using the new Belimo Room Display App, which turns your smartphone into a remote display. The NFC apps associated with Belimo's room sensors can be password protected for an added layer of security.
