EE895 Miniature-Sensor Module: CO₂, Temperature, Barometer - DESCRIPTION
by E+E Elektronik

A Single Module - 3 Measurands:
The EE895 module measures not only the CO₂ concentration up to 10,000 ppm (1% CO₂) but also the temperature (T) and ambient pressure (p). The pressure and temperature compensation with onboard sensors minimizes the impact of the environment on the CO₂ measurement. As a result, the EE895 offers exceptionally high CO₂ measurement accuracy, independent of altitude or changing ambient conditions.

Long-Term Stable CO₂ Measuring Principle:
The dual-wavelength NDIR CO₂ measuring principle with auto-calibration ensures excellent long-term stability, as it automatically compensates for aging effects and is particularly resistant to contamination. The multi-point CO₂ and temperature factory adjustment procedure leads to superior CO₂ measurement accuracy over the entire T working range from -40...60°C (-40...140°F).

Easy Design-In:
The I²C and UART interfaces, the very small dimensions of only 35 mm x 15 mm x 7 mm (1.38" x 0.6" x 0.27"), and various mounting options facilitate the design-in of the sensor module.

Easily Configurable:
The setup of the EE895 module via the digital interface makes it easy to configure—for example, the CO₂ measurement interval setup according to the application and the power requirements.

EE895 Evaluation Board for Test Purposes:
The evaluation board, which is available as an accessory, allows easy testing of the EE895. It will enable you to test with a view to the intended application. It connects to the PC via a USB cable, and using the free sensor evaluation software, the measurement data is visualized and logged. Users can set the EE895's measurement interval and the desired measurement units for temperature and pressure.

Design Data and Support Literature:
The electronic design data of the EE895 is available free of charge from the download area of the E+E website. The 3D data from the sensing module interfaces easily with a CAD design tool. By the use of the I²C interface, the EE895 module, when connected to various single-board computers, and step-by-step instructions (available from the download area), help you program and integrate the EE895 into your application.
