EE240 Series
Wireless Sensor for
Humidity / Temperature / CO
2
State of the art sensor technology, highest reliability of data
transmission and the ease of system installation are the outstanding
features of the wireless sensor series EE240.
Wireless Transmitter EE245
The elegant housing combines the measurement of temperature,
humidity and CO
cation. As a standard, batteries provide for the power supply. For more
power demanding applications the device can be powered through an
external adapter.
Wireless Transmitter EE244
The industrial housing can be equipped with up to three sensing probes
to contact the interchangeable probes. An optional display is available to
provide local indication. As a standard, batteries provide for the power
supply. For more power demanding applications the device can be powered through an external adapter.
Interchangeable Sensing probes
A modular structure and easy extendable assortment of sensing probes
allow the usage in many applications. For many years, the proven
sensor technology of E+E for the measurement values of humidity, temperature, and CO
longtime stability.
The standard interface and the stored calibration data of the sensing
probe allow for any choice or combination of the available sensing
probes offered. An adaptation or expansion of the number of sensing
probes afterwards or an exchange for service purposes can be achieved
in seconds – a must-have for uninterrupted data acquisition. For high
temperature applications or installations in small spaces, the sensing
probe can be connected with a sensor cable of up to 10 m
. An optional display is available to provide local indi-

Sensing Probes for EE244
Base Station EE242
The EE242 base station is the central component of a wireless network
with up to 500 transmitters or up to 2000 measured parameters. With the
base station and the integrated web server one can easily perform the
setup of the entire wireless network.
EE242 allows for easy remote access and diagnosis of the network.
The measured data is available at the EE242 base station via Ethernet /
Modbus TCP and RS485 / Modbus RTU. Four measured parameters
can be selected to the analogue outputs (0 - 5 / 10 V or 4 - 20 mA).
Measured data and status information are available also on the optional
display.
Router Series EE244-R
The radio range is greatly depending on local circumstances. With the
router series EE244-R obstacles can be bypassed or the transmission
distance expanded.

Highest Transmission Reliability
The data transmission is based on the IEEE 802.15.4 protocol with a transmission frequency of 2.4 GHz,
which can be used all over the world without any additional cost. A special identification address, checksums,
handshakes, and bidirectional communication provide the highest transmission reliability. Typical radio ranges
are 60 m
(197 ft) for indoor applications and 1000 m (3300 ft) in the open field. Greater radio ranges are easy
obtainable with routers. The self-configuring, scalable, and self-healing mesh network, even when a
connection fails, is another component contributing to the improvement of the transmission reliability and
security. The highest possible data security level is accomplished with a preset encryption key according to
AES-128.
Parallel Operation
Parallel operation of several EE240 wireless networks (i.e. several base stations) is also possible. For this each
transmitter and router may be within the transmission range of the routers and basis station of one network only.
Digital Bus Connection
For bus integration, Modbus is supported. Communication is implemented via Ethernet or RS485 interface.
