Questions about our products?

Well proven humidity sensor element, state-of-the-art ASIC technology and highly accurate humidity and temperature adjustment represent the basis for outstanding performance of the digital humidity and temperature sensor EEH110.

The proprietary E+E coating protects the active sensor surface of the digital humidity sensor against dirt and corrosion, which leads to excellent long-term stability even in polluted environment. The measured values are available on the digital interfaces I2C, PWM and PDM as well as on an analog voltage output.

Precise humidity and temperature factory adjustment ensures a high accuracy of ±2% RH and ±0.3 °C (±0.5 °F).

The 5 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.

  • Eval Kit EK-2-110

    Evaluation Kit for digital Humidity Sensor EEH110

    The evaluation kit facilitates the evaluation and testing of the digital humidity and temperature sensors.

    The EvalKit EK-2-110 consists of:

    - USB Dongle with cable and plug for connecting the sensor to a PC.
    - EEH110 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.

    Suitable for Products:


  • How many E+E devices can be connected on one bus to a controller with i²C interface?

    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.

  • 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.
