CDS201-Room Sensor for CO₂, Temperature and Relative Humidity
- The CDS201 is optimised for demand controlled ventilation and building automation in residential and commercial applications. The versatile room sensor combines CO2, temperature (T) and relative humidity (RH) measurement in one device with modern design and state-of-the-art technology. The elegant enclosure is available in two sizes (EU and US format) and features an optional display.

Outstanding Measurement Performance
- The CO2 measurement of the CDS201 relies on the pollution-resistant E+E dual wavelength NDIR technology. This measuring principle automatically compensates for ageing effects and ensures excellent long-term stability. The multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range.
- The E+E proprietary sensor coating protects the RH/T sensing element from contamination and corrosive deposits. This improves the measuring performance and service life of the sensing element in dusty or dirty environments.
- Outputs and Digital Interface
- The CDS201 room sensor features analogue outputs or RS485 interface with Modbus RTU or BACnet MS/TP protocol. In the digital version, the CDS201 also calculates the dew point temperature (Td). The measured values can also be read locally on the optional graphic display.The version with RS485 interface can be set up and configured via PC with the free PCS10 Product Configuration Software and an optional configuration adapter.
- Installation-friendly Enclosure
- The enclosure of the CDS201 facilitates fast and thus cost-saving installation. The back cover with the push-in spring terminals can be mounted and wired without the front cover. This means that the electronics, which are accommodated in the front cover, are not exposed to construction site pollution. Before commissioning, the active part can be simply snapped onto the back cover. Besides, the electronics part can be replaced without tools within seconds.
