Since launching our groundbreaking range of Alphasense PPB Air Quality sensors back in 2014, we have continued to prioritise the development of lowcost sensors with the aim of improving global air quality. Following extensive RD in the field of Volatile Organic Compounds, we are delighted to announce the launch of two new electrochemical sensors, the VOCA4 and VOCB4, both of which …

20190926· The data acquired from the lowcost air quality sensors monitor dust particles, toxic odor gases, along with weather parameters within a single enclosure. For instance, a single air quality monitor can measure PM1, , PM10, SOx, NOx, CO2, CO, TVOCs, etc. along with meteorological parameters like wind speed and direction, relative humidity, ambient temperature, pressure, light …

Lowcost VOC sensors suggest a promising future to provide additional and complementary information to conventional VOC measurement techniques. Although these sensors have been widely used for industrial purposes, there are limited studies deploying these sensors for residential or ambient measurement because of a high limit of detection (LOD) and nonselectivity. LOD can be decreased …
