The room wireless transmitter EE245 is based on the IEEE 802.15.4 protocol with a transmission frequency of 2.4 GHz and measures up to three physical quantities: relative humidity, temperature and CO₂.
The sensor is designed especially for applications in offices, museums and living rooms.. The measured values for humidity, temperature and CO₂ can be read on an optional display. The EE245 can be powered either by batteries or by an external power supply.

Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
