Temperature and Relative Humidity

CDS201 Room Sensor for CO2, Temperature and Relative Humidity The CDS201 is optimized for demand controlled ventilation and building automation in residential and commercial applications. Versatile The CDS201 combines CO2, temperature (T) and relative humidity (RH) measurement in one device with modern design and state-of-the-art technology. Outstanding Measurement Performance The CDS201 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long-term stability.

FeaturesMeasurement performance ■ High CO2 / RH / T accuracy ■ Excellent long term stability ■ State-of-the-art E+E sensing elements ■ CO2: NDIR dual wavelength - Protected by E+E proprietary coating - Patented sensor technology ■ Innovative design avoids false air ingress ■ Time saving installation and wiring ■ Snap-on without tools ■ Push-in spring terminals ■ All electronics inside the front cover ■ Smooth cover surface ■ UL94HB approved enclosure material Outputs ■ Three analogue outputs ■ RS485 interface with Modbus RTU ■ Large graphic display Available via E+E certificate service

Features Protective Sensor Coating The E+E proprietary sensor coating is a protective layer applied to the active surface of the RH / T sensing element. The coating substantially extends sensor lifetime and ensures optimal measurement performance in corrosive environment (salts, off-shore applications). Additionally, it improves the sensors’ long term stability in dusty, dirty or oily applications by preventing stray impedance caused by deposits on the active sensor surface.
