EE894 – Digital CO2 Module

Sensor module for CO2, humidity, temperature and pressure

There are no PDF's for this product

The digital sensor module EE894 from E+E Elektronik measures carbon dioxide (CO2), relative humidity (RH), temperature (T) and ambient pressure (p). Temperature and pressure compensation ensures high CO2 measurement accuracy under changing environmental conditions. Very small dimensions and the I2C or E2 interface facilitate the design-in.

The EE894 module is ideal for demand controlled ventilation and building automation. It incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long-term stability.

A multi-point CO2 and T factory adjustment leads to excellent CO2 measurement accuracy over the entire T working range. The pressure compensation minimizes the impact of altitude and ambient pressure variations onto the CO2 readings.

The measured data, with a range of up to 1% CO2 (0…10000 ppm), is available on the I²C or the E2 digital interface. Small dimensions and electrical connection via contact pins and pads facilitate the design-in.

The EE894 is available in two sizes and with various electrical connection options. Due to low current consumption, it is ideal for battery-operated devices.
