Zest_Sensor_Potentiostat

Overview

The Zest_Sensor_Potentiostat is an electronic development board for 6TRON open source platform based on two NO2(nitrogen-dioxide) sensors from Alphasense.

Sensor 1 :NO2-B43F : configured for small range of nitrogen-dioxide concentration

  • Dectection principle : fuel cell technology

  • NO2 detection sensitivity of 15ppm

  • NO2 detection range from 0 to 20ppm

Sensor 2 : NO2-AE :configured for large range of nitrogen-dioxide concentration

  • Dectection principle : fuel cell technology
  • NO2 detection sensitivity of 0.1ppm
  • NO2 detection range from 0 to 200ppm

The Zest_Sensor_Potentiostat board can be used to monitor Nitrogen Dioxide concentration and air quality in health, environmental and industrial applications.
