A Single Module – 3 Measurands

Additionally to CO₂ concentration up to 10 000 ppm the EE895 module measures also the temperature and ambient pressure. The pressure and temperature compensation with on-board sensors minimizes the environmental influences onto the CO₂ measurement. Thus the module offers a constantly high CO₂ measurement accuracy, independent of altitude or changing ambient conditions.

Long-Term Stable CO₂ Measurement Principle

The dual wavelength NDIR CO₂ measuring principle with auto-calibration ensures long-term stable measurements, as it automatically compensates for aging effects and is particularly resistant to contamination. The factory multi-point CO₂ and temperature adjustment procedure leads to an excellent CO₂ measurement accuracy over the entire temperature working range of -40...60 °C (-40...140 °F).

Easy Design-In

The measured data for CO₂, temperature and pressure is available on the I2C or UART interface. 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.

Flexibly Configurable

The EE895 module can be flexibly configured via the digital interface. The CO₂ measurement interval can be set according to the application and the power requirements.

Evaluation Board for Testing on a PC

With the separately available EE895 Evaluation Board, the sensor module can be tested on a PC. The free evaluation software displays the measurement data in graphical form and allows the user to set the sampling rate and the measurement units for temperature and pressure. For further processing, the data can be saved as .CSV file.
