Digital Humidity and Temperature Module


The EE03 is an accurate humidity and temperature digital sensor with serial two-wire interface and a simple E2 protocol.

EE03 humidity and temperature sensor module with flange

EE03 humidity and temperature sensor module

Originally designed for the automotive industry, EE03 can be used as stand alone device or as plug in module for data loggers, handheld and other devices. Due to its construction EE03 is ideal for monitoring surface humidity and temperature and especially for detecting near-condensation (dew point) conditions.

The E+E proprietary sensor coating allows for EE03 to be employed even in aggressive and corrosive environment. Customised versions are possible.

How many E+E devices can be connected on one bus to a controller with E2 Interface?

Only one E+E device can be connected to the E2 interface of a controller.

Which is the maximum cable length of E2 Interface?

The maximum cable length depends on the product, clock speed and pull-up resistor, and can be up to 10m. For detail please see E2 interface for humidity probes/modules

What is the difference between a 2 wire and a 3 wire current output?

Transmitter with “two-wires” technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology “three-wires” the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
