EE071 is optimized for use in demanding OEM applications.
In addition to the precise measurement of humidity (RH) and
temperature (T), the EE071 calculates physical quantities such
as dew point temperature, mixing ratio and absolute humidity.
All measured and calculated values are available on the
RS-485 interface with Modbus RTU protocol.
The RH and T sensor HCT01 is perfectly protected against dust
and dirt by the E+E proprietary coating. Furthermore, all solder
pads are sealed against corrosion. With the appropriate filter
cap the EE071 offers outstanding long term stability even in
harsh environment. The compact design with M12 connector
allows for easy installation and fast replacement of the probe.
With the optional Modbus configuration adapter the user can
perform RH and T adjustment and set the Modbus parameters.

The measured values are saved as a 32Bit float value from 0x19 to 0x25 and as 16Bit signed integer
between 0x27 and 0x2D.
The factory setting for the Slave-ID is 247 as an integer 16Bit value. This ID can be customised in the
register 0x00 (value margin 1 - 247 permitted).
The serial number as ASCII-code is located at register address 30001-30008.

E+E Sensor Coating
The E+E proprietary sensor coating is a protective layer applied to the active surface of the HCT01 sensing
element. The coating extends substantially the lifetime and the measurement performance of the E+E sensor
in corrosive environment. Additionally, it improves the sensor’s long term stability in dusty, dirty or oily
applications by preventing stray impedances caused by deposits on the active sensor surface.
