E+E EE03 Specifications

EE03

EE03 is a cost effective, highly accurate temperature and humidity
measurement module with two-wire digital interface. It features the
well-proven, long term stable E+E HC103 humidity sensor. The EE03
is optimized for best thermal coupling with a plane surface, which is
paramount for accurate measurement of surface moisture. By this,
besides ambient humidity measurement, the EE03 can be employed
also as condensation monitor, and indicates the danger of
condensation before condensation actually occurs.

The E+E proprietary sensor coating is a protective layer applied to the
sensing element. The coating extends substantially the life-time and
the measurement performance of EE03 in corrosive environment.
Additionally, it improves the long term stability in dusty, dirty or oily
conditions by preventing stray impedances caused by deposits on the
active sensor surface.

Humidity and Temperature Module

with Digital Output

The E2 digital protocol allows for easy design in. An E2-RS232
convertor facilitates the testing of EE03 during the design in process.
