EE CDS201 ROOM SENSOR | \(CO_{2}\), HUMIDITY & TEMPERATURE TRANSMITTER

The EE CDS201 by E+E Elektronik is an advanced room sensor designed for simultaneous measurement of \(CO_{2}\), temperature (\(T\)), and relative humidity (\(RH\)) in indoor environments.

A versatile 3-in-1 room sensor for \(CO_{2}\), temperature, and relative humidity, optimized for demand-controlled ventilation and building automation.

EE CDS201 ROOM SENSOR | \(CO_{2}\), HUMIDITY & TEMPERATURE TRANSMITTER

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.

The CDS201 combines high-accuracy sensing with a modern, installation-friendly design. It utilizes E+E’s dual-wavelength NDIR \(CO_{2}\) sensor technology, which compensates for aging effects and provides exceptional long-term stability even in polluted environments. The humidity sensing element is protected by a proprietary E+E coating to ensure reliability in dusty or corrosive conditions. It is available with analog outputs (0-10 V or 4-20 mA) or a digital RS485 interface (Modbus RTU or BACnet MS/TP).

PRODUCT USES:

  • Demand-controlled ventilation (DCV) in residential and commercial buildings.
  • Building automation systems (BAS).
  • Indoor air quality monitoring in offices, schools, and hospitals.
