Miniature Sensor Module for CO₂, Temperature and Barometric Pressure The EE895 3-in-1 sensor module is an ideal choice for measuring devices for demand controlled ventilation, building automation or for process control. Due to the low power consumption, the module is also suitable for battery-operated devices such as hand-held meters, data loggers or wireless transmitters. 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). EE895 Evaluation Board for Test Purposes The evaluation board, which is available as an accessory, allows easy testing of the EE895 with a view to the intended application. It is connected to the PC via a USB cable. Using the sensor evaluation software, which is available free of charge, the measurement data can be visualised and logged. Users have the option to set the EE895's measurement interval, and the desired measurement units for temperature and pressure.
