Miniature CO2 sensor EE895

NDIRI2CUART

Miniature Sensor Module for CO₂, Temperature and Barometric Pressure The EE895 is the ideal measurement module for sensors and transmitters used in demand controlled ventilation, building automation and process control. Due to the low power consumption, the module is also suitable for battery operated devices such as handhelds, data loggers and wireless transmitters. CO₂ Measurement Performance The CO₂ measurement is based on the dual wavelength NDIR principle, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. A multiple point CO₂ and temperature factory adjustment procedure leads to excellent CO₂ measurement accuracy over the entire temperature working range. Versatile: 3 in 1 Besides CO₂, the EE895 also measures temperature (T) and barometric pressure (p). The temperature and pressure compensation with on-board sensors minimises the impact of altitude and ambient conditions onto the CO₂ measured data. Digital Interfaces The CO₂, temperature and pressure measured data is available on the I²C or the UART digital interface. Configurable The EE895 can be configured via digital interface. The CO₂ measurement interval can be set according to the application and the power requirements.
