EE244 Wireless Industrial Transmitter
(CO2 Temp RH)


Key Features

Up to 3 sensors may be plugged into each transmitter. If required, connection cables of up to 10 metres are available for remote sensors. Measurement values for humidity, temperature and CO2 may be shown on an optional display. The wireless transmitter is powered by batteries, but can also be connected to an external power supply. Depending on the measuring rate and variables, the battery life may last up to 3 years.

  • Measurement of temperature, humidity and CO2
  • One wireless network can contain up to 500 transmitters
  • Interchangeable sensors
  • Remote sensors at up to 10 meters
  • Uses four 1.5 V AA standard batteries
  • Battery life of up to 3 years
  • External power supply possible
  • Optional display


Interchangeable sensors from E+E

Different digital sensors for humidity, temperature and CO2 are available for the wireless transmitter EE244. Plugging in or replacing sensors during operation can be done in a matter of seconds, completely hassle-free.

The combination of digital sensors with the EE244 wireless transmitter is particularly suited for industrial applications, since calibration of the sensors will not influence the operation of the wireless network.

EE244 Wireless Industrial Transmitter


  • Measures CO2 Temp & Humidity
  • 2.4 GHZ communication
  • Uses IEE 802.15.4 communication protocol
  • Transmission distance of 1000 m (3000 ft) in open field
  • Must be used with EE242 Base Station




Available Sensors Include:



Key Features

The base station EE242 is used to configure the entire wireless network and to log measurement data. The integrated web server allows the user to adapt the wireless network individually and conveniently via the digital Ethernet interface without requiring additional software on your PC. Modbus (RTU and TCP/IP) is supported for integration in a bus system. Four analogue outputs are also available for further processing of the measurement values.

  • Option of administrating up to 500 transmitters
  • Web server
  • Ethernet interface
  • Modbus (RTU and TCP/IP)
  • 4 analogue outputs
  • 4-line display
  • DIN rail mounting
