20200917· However, GSE NO 2 sensors are susceptible to crossinterference from ozone (O 3) when measuring the outdoor air. We have tackled this issue by developing a new 01 ppm nitrogen dioxide (NO 2) sensor head that contains an integrated ozone (O 3) filtering layer. This gives you an accurate way to measure the air, by removing the ozone interference. The challenges of measuring nitrogen dioxide …

On the basis of firstprinciples calculations, we demonstrate the potential application of silicene as a highly sensitive molecule sensor for NH3, NO, and NO2 molecules. NH3, NO and NO2 molecules chemically adsorb on silicene via strong chemical bonds. With distinct charge transfer from silicene to …

20210101· The sensor was further fabricated to detect of nitrogen dioxide (NO 2) and ammonia (NH 3) gas at low concentration (8 ppm). The sensing effects toward NO 2 and NH 3 gases were compared between low and hightemperature gases. The WO 3 /PS sample exhibited the highest sensitivity (%) for NO 2 gas at 200 °C. The sensitivity of both gases ...

Sensors should be placed in areas where there is little or no air movement and in locations of good air circulation but not in the path of rapidly moving air which is likely to have diluted concentrations of CO and NO2. Sensor location at entrances to the parking facility, elevators, makeup air fans and any other sources of active air currents should avoided as this will result in reduced ...

This is a typical range for many pollutant gases (NO2, O3, CO, etc) in nottoopolluted environments, like EU or USA cities. In the graph we also see 2 green lines. They represent the maximum and minimum readings that we can expect from the Libelium sensor. We obtained these 2 lines easily: we simply added (and subtracted) to the red line (real concentration) the accuracy of the sensor (which ...
