The proprietary E+E coating protects the active sensor surface against dirt and corrosion, which leads to excellent long-term stability even in polluted environment.
Precise humidity and temperature factory adjustment ensures a high accuracy of ±2% RH and ±0.3 °C (±0.54 °F). The measured values are available on I2C, PWM, PDM and SPIdigital interfaces.
The 3 V supply voltage increases the versatility of the digital humidity and temperature sensor. With very small dimensions, the sensor can also be used in applications with space restrictions.

The evaluation kit facilitates the evaluation and testing of the digital humidity and temperature sensors.
The EvalKit EK-3-210 consists of:
- USB Dongle with cable and plug for connecting the sensor to a PC.
- EEH210 sensor soldered on a test board.
- Software to monitor and save the measured values.
The cable, plug and test board can be exposed to temperatures from -40 to 125 °C (-40...257 °F). Therefore the sensors can be tested over their entire temperature and humidity working range.
Each I²C devices does have it's own ID by series, as long as this ID is unique in the bus this module or component could get built into the bus.
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.
