The Yocto-CO2-V2 device lets you measure the quantity of carbon dioxide (CO2) in ambient air as well as the relative humidity, temperature and atmospheric pressure via an USB connection. It can record the measurements on its internal flash for later retrieval when connected again by USB.
This device is ideal to precisely monitor the air quality in residential, commercial and industrial spaces, as well as potentially dusty air ducts used in HVAC (Heating Ventilation and Air Conditioning) systems. The sensor used in this device uses non-dispersive infra-red absorption (NDIR), and requires no maintenance. It provides accurate measurements already within the first minute after power on.
The expected CO2 concentration in fresh air varies between 360 and 400 ppm depending on the location. Industry consensus standard rates maximal admissible CO2 between 1'000 and 2'500 ppm in ventilated buildings. Around 10'000 ppm, some people feel dizziness. This sensor is capable to measure up to 40'000 ppm (vol) or 4%, with a well-defined accuracy in the range 0...10'000 ppm (25Ѓ).
This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
