E+E Gas sensor module EE894-HV2 Suitable for gases: Carbon dioxide

The used NDIR dual-beam method with auto-calibration is particularly stable over the long term and insensitive to contamination. Factory multi-point CO2 and temperature adjustment, along with excellent temperature compensation, enable precise CO2 measurements over a wide temperature range. The influence of ambient pressure on CO2 measurement accuracy is automatically compensated by the integrated pressure sensor. Measurement data with a range of up to 0.5% CO2 is available on the digital I2C interface. Typical applications include controlled indoor ventilation, building management, data loggers, handheld measuring devices, and wireless transmitters.
