The EE244 modular wireless transmitter/router is based on the IEEE 802.15.4 protocol with a transmission frequency of 2.4 GHz and measures relative humidity and temperature.
The EE244 accomodates up to 3 sensing probes, which can be plugged directly onto the EE244 enclosure or remotely installed with connection cables up to 10m. The robust enclosure features an external antenna and an optional display.
The device can be powered by four alkaline AA batteries or by external power supply. Depending on the number of probes, the measureands and the sampling and transmission rate, the batteries may last up to 3 years.

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.
