CO2/Temperature/Humidity/Differential Pressure Digital Sensor Module EE895
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 (auto-correction function). ● Revolutionary long-term stability. ● Temperature/pressure compensation function. ● Low power consumption. ● Compact. ■ The EE895 is ideal for ventilation control and general building air conditioning management applications. Due to its low power consumption, it is also suitable for battery-operated devices such as handheld units, data loggers, and wireless transmitters. ■ To compensate for aging degradation, E+E's unique dual-wavelength NDIR CO2 sensor is employed, which is resistant to contamination and provides long-term stability. It performs accurate measurements across all temperature ranges. ■ In addition to CO2 measurement, it can also measure temperature (T) and differential pressure (p). The temperature and pressure compensation from the included sensors minimizes the impact of altitude and external environments on CO2 measurements. ■ The measurement values for CO2, temperature (T), and differential pressure (p) can be output digitally via I²C or UART. Settings can be configured through digital communication. The measurement interval for CO2 can be set according to application and power conditions.
