Presentation of the pollution sensor :

The monitoring system will meet constraints such as:

  • low weight;
  • limited dimensions;
  • low cost;
  • autonomy and low energy consumption;
  • adapted air sampling;
  • accurate monitoring.

Electrochemical and metal oxide sensors are used for monitoring of VOCs, NO2 and O3 concentrations, due to their crucial role in outdoor air photochemical polution, in particular during summer.

Additionally, sensors for Temperature (T), Relative Humidity (RH) and Pressure (P) will enable the determination of meteorological conditions of the investigated air sample.

Fluidic (electrovalves, pumps, microfluidics chips, gastight enclosures) and electronic (battery, GPS) elements will be integrated, as they are necessary for the development of a functional and autonomous system.

The system conception is already completed along with 3D designs which are used for fluidic simulations.

A laboratory prototype has been developped for the calibration of sensors and for preliminary tests.
