THE AVENGERS Measuring Atmospheric Ozone and NOx gases
General • 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.
Science • 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.
Technical • 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.
