Description
The Swiss-made Yocto VOC Sensor allows you to estimate the quantity of volatile organic compounds (VOCs) in ambient air via an USB connection, as well as record it on its internal flash for later retrieval when connected again by USB.
This device is ideal to monitor the air quality in residential, commercial and industrial spaces. The MEMS metal oxide sensor used in this device measures the variation of total volatile organic compounds in ambiant air, and use it to estimate their concentration in ppm CO2 equivalents (relative). The sensor is able to detect alcohols, aldehydes, aliphatic hydro-carbons, amines, aromatic hydro-carbons (petrol vapors, etc.), carbon oxides, CH4, LPG, ketones, and organic acids. Be aware that the first estimation is only available 15 minutes after powering on the device.
The initial value returned by the sensor is 450 ppm CO2 equivalents (theoretical value for fresh air). The sensor measure relative variations of volatile organic compounds to provide an estimated ppm value, with an automatic baseline correction. The absolute value must therefore be interpreted with great care, as it is subject to drift. It is not comparable with the absolute value returned by a Yocto CO2Â for instance, but it has the advantage of including a broader range of volatile organic compounds than a simple CO2 sensor.
The sensor part can be split from the main USB board and moved several meters away using ribbon cable, soldered on the designed contact pads. This may be useful to move the sensor in close proximity to HVAC ducts.
The Yocto-VOC is not available anymore. It has been replaced by the Yocto VOC V2Â which has identical characteristics, except for a shorter warm-up time (5-6 min instead of 15 min)..
This device can be connected directly to an Ethernet network using a YoctoHub Ethernet, to a WiFi network using a YoctoHub Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub GSM.
USB cables and enclosure to be ordered separately.
