E+E Elektronik CO2/Temperature/Barometric Pressure Mini Sensor Module EE895

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 on-board sensors minimizes the impact of the environment onto the CO2 measurement. As a result, the EE895 offers a particularly 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 excellent 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. Flexibly Configurable The EE895 module can be configured via the digital interface. The CO2 measurement interval can be set according to the application and the power requirements. EE895 Evaluation Board With the optional evaluation board, the sensor module can be easily tested with regard to the intended application. Typical Applications Demand controlled ventilation Building automation Process control Data loggers, hand-held instruments Wireless transmitters
