Computations in analog electrical sensors

Sep 29, 2019· 1. We begin by giving a logical name to each input: t for the temperature, NO2_We for the measure on the NO2 work electrode, NO2_Ae for the auxiliary electrode, and so on. These name correspond to those used in the Alphasense application note and this will therefore make our work easier to input the formula in the next step.

Alphasense OPCN2 — VAQUUMS project website

The Alphasense OPCN2 is an optical particle counter. According to the manufacturer, the flow correction of this sensor ensures stable readings, even in high dust environments. The OPCN2 measures particles from micron to 17 micron diameter at a 1 second interval. The OPCN2 provides both PM readings and real time particle size histograms.

Ozone Sensors | O3 Sensor | Alphasense

The patented (and patent pending) Alphasense solution is to combine the Nitrogen Dioxide (NO2B43F or NO2A43F) and oxidising gas (OXB431 or OXA431) sensors as a pair: the NO 2 sensor measures only NO 2 and the difference between the two sensors gives the Ozone concentration. Gas concentrations for both O3 and NO 2 are typically 20 to 200 ppb ...
