OMNIO - CO2-Sensor

Presentation

The CO2-sensor is a wired radio sensor to capture the concentration of carbon dioxide (400…2550 ppm) in the air. The measured values are transmitted wireless to Omnio gateways. It is particularly used to control the air quality indoors in offices, schools, hotels and residential premises. EnOcean Equipment Profile (EEP) A5-09-04.

Product Description

This sensor gives information concerning carbon dioxide (CO2) concentration levels, essential element in air quality monitoring and control in occupied buildings. Changes in concentration of this gas are difficult for humans to recognize. The gas is safe in low concentrations (typically <1000ppm), however prolonged exposure at moderate levels can lead to a range of health related problems such as sick building syndrome causing fatigue like symptoms, effects are most notable in children –kindergartens, schools- due to their higher metabolic activity.

Current and incoming legislation requires CO2 gas monitoring within building environments for optimal control of air quality. Moreover, such CO2 gas monitoring is employed within demand control ventilation systems used for building heating ventilation and air conditioning.

Application areas

Indoor Air Quality Measurement in Offices, Schools, hotels and residential areas 
DCV- Demand Controlled Ventilation for energy savings HVAC applications for building management 
Home air quality control
