De sensordata voor NO2 die het RIVM momenteel op het Samen Meten Dataportaal toont, is gemeten met de NO2-B43F. Het RIVM past een kalibratieprocedure toe om te komen van het sensorsignaal (elektrische spanning) tot de getoonde NO2 concentratie. De sensor heeft als output elektrische spanningssignalen.

Alphasense NO2 Sensors . Alphasense Nitrogen Dioxide Sensors (NO2 Sensors) are available in a wide range of formats and both PPM and PPB variants, making them suitable for use in variety of applications, from fixed and portable detection instruments to environmental monitoring systems and networks. A: 20mm diameter, the industry standard size for portable gas detectors B: 32mm diameter …
Please note we have developed tailor made signal boards for this sensor, which can be purchased separately. Contact us for more details about application of this sensor or various signal boards suitable for this sensor. Model: NO2-B43F Brand: Alphasense Material: mixture Origin: other overseas regions Output model category: analog sensor Working principle: gas sensor Applicable […]
The sensor signal is read by a 16 bit analogue-to-digital (A ∕ D) converter (ADS1115). Of the 16 devices, 2 (SD01 and SD02) use model NO2-B42F for NO 2 measurements and the other 14 use the newer NO2-B43F sensor. Of the 16 sensor devices, 12 are also equipped with a Shinyei PPD42NS sensor in order to measure particulate matter optically.
The LCMs were designed and constructed at the University of Washington. Each LCM was built with four electrochemical gas sensors—CO-B4, NO-B4, NO2-B43F, and OX-B431 (Alphasense Ltd., Great Notley, UK)—which detect CO, NO, NO 2, and O 3 + NO 2, respectively . These gas sensors were selected because of their price (USD ~200), availability of ...
NO2 (NO2-B43F) electrochemical gas sensors. The sensors were deployed in two phases over a period of 3 months at sites situated within two megacities with diverse geographi-cal, meteorological and air quality parameters. A unique fea-ture of our deployment is a swap-out experiment wherein three of these sensors were relocated to different sites ...
The patented (and patent pending) Alphasense solution is to combine the Nitrogen Dioxide (NO2-B43F or NO2-A43F) and oxidising gas (OX-B431 or OX-A431) sensors as a pair: the NO 2 sensor measures only NO 2 and the difference between the two sensors gives the Ozone concentration.
Alphasense NO2-B4. The Alphasense NO2-B43F is a medium cost sensor which measures nitrogen dioxide. According to its specifications it is able to measure differences of 5-10 ppb in outside conditions if it is used together with the Alphasense low noise electronics. This sensor is used in some citizen science projects. Pollutant (s) : NO2.
· The differential NO2-B43F sensor response (Figs. 3d and 4c) indicates a strong temperature dependence that is not com- pensated for by the auxiliary electrode, suggesting that addi-
· For this reason, it is important to put the NO2-B43F and the OX-B431 sensors on the same Yocto-MaxiMicroVolt-Rx. Note that the factor of crossed sensitivity to NO2 of the OX-B431 should be provided by Alphasense, but it hadn't been communicated to us. A simple email to Alphasense support allowed us to obtain the missing coefficient, as Alphasense keeps in a database the measured …
Alphasense B43F NO2 meten met sensoren op het USP | 06 December 2017 5 We gebruiken momenteel de Alphasense B43F NO2 sensor, in combinae met het “ Individual Sensor Board” (ISB) van Alphasense. Het ISB is duurder dan de sensor zelf maar lijkt het geld wel waard. De twee uitgangsspanningen van het USB worden met een 16bit ADC uitgelezen.
· Hi rajhefondo. I hope you had finished your project successfully! I’ve read that you have work with AlphaSense sensors and I’d like to know how you’ve made the connections between those sensors and Arduino board because I have to do a project using this board with AlphaSense sensors, however, I didn’t found any information about that.

Die patentierte (und zum Patent angemeldete) Lösung von Alphasense besteht darin, die Sensoren für Stickstoffdioxid (NO2-B43F oder NO2-A43F) und oxidierende Gase (OX-B431 oder OX-A431) als Paar zu kombinieren: Der NO2-Sensor misst nur NO2 und die Differenz zwischen den beiden Sensoren ergibt die Ozonkonzentration. Die Gaskonzentrationen sowohl für O3 als auch für NO2 liegen typischerweise ...
sensor system). Clearly, the Alphasense NO 2-sensors systematically show the lowest standard deviations ( µg/m3, when averaged over the entire experiment) and relatively small differences between sensors. Next ‘best’ are the Membrapor 1 ( µg/m3) and Membrapor C20 ( µg/m3) while the Cairclip systems indicate a much higher value (
· The AirSensEURs contain electrochemical sensors from AlphaSense. Several sources like RIVM, state that these sensors are more accurate (than metaloxide sensors), but at the same time need per-sensor calibration. Within the ASE boxes the following four gas-sensors were applied: NO2 (Nitrogen Dioxide): the NO2-B43F, see datasheet.

Pollutant gases, such as CO, NO2, O3, and SO2 affect human health, and low-cost sensors are an important complement to regulatory-grade instruments in pollutant monitoring. Previous studies focused on one or several species, while comprehensive assessments of multiple sensors remain limited. We conducted a 12-month field evaluation of four Alphasense sensors in Beijing and used single linear ...
