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.
