Measuring Atmospheric Ozone and NOx gases


  • The primary goal of the ITO sensor project is to measure the concentration of Ozone (O3) and NOx (NO, NO2) gases as the function of altitude.

  • The concentration of these gases will specify the current situation of ozone depletion.

  • These measurements will be compared to past measurements made by other payloads.


  • The measurement from the sensor is done as the function of physical quantities as the sensor might function in a different way depending on the altitude, temperature, humidity and pressure.

  • The obtained measurements are compared with various experiments showing the precise concentration of Ozone and NOx gases.

  • Different halogens, such as Flourine, Chlorine, and Iodine have been used to accelerate this process.


  • The concentration of Ozone and NOx gases is calculated as the function of voltage produced across the sensor.

  • As the resistance in the ITO sensor varies with the concentration of these gases, different voltages are produced with the same amount of input current in the circuit board.

  • The Real Time Clock will be utilized as a counter and a timestamp will be printed for each measurement so that it can be related by time to altitude.
