CO2/Temperature/Humidity/Differential Pressure Digital Sensor Module EE894
The measurement principle adopts the NDIR method (non-dispersive infrared absorption)! For integration into OEM equipment, HVAC, and agricultural-related devices!
● The detection principle recommended by the Ministry of Economy, Trade and Industry for CO2 measuring devices is an optical sensor. ● Equipped with automatic calibration function (automatic correction function). ● Revolutionary long-term stability. ● Temperature/pressure compensation function. ● Low power consumption. ● Compact (45 mm * 22 mm * 15 mm). ■ The EE894 is a digital sensor module suitable for ventilation control and general building air conditioning management applications for CO2/temperature/humidity/differential pressure. ■ To compensate for aging degradation, it adopts E+E's unique dual-wavelength NDIR CO2 sensor. ■ It is resistant to contamination and provides long-term stability. In addition to CO2 measurement, it can also measure humidity (RH), temperature (T), and differential pressure (p). For more details, please download the catalog or contact us.
