Atmotube constantly monitors air pollution in real time. We utilize a MOX-based (Metal-oxide) sensor in our product. The functionality of a MOX gas sensor is based on the conductivity-change of the gas-sensitive MOX semi-conductor layers at gas exposure, which can be externally measured and analyzed. A specific MOX gas-sensitive layer reacts to oxidizable gases with increasing of the layer resistance and to reducible gases with decreasing of the layer resistance.
