Evaluation of budget carbon monoxide sensor for atmospheric measurements

Atmospheric air is the most important component for living organisms. During the technological revolution, the environment is the most pressing global issue. As a result of human activity, large amounts of harmful and poisonous gases are released into the environment. In the largest cities in the world and in places where heavy and chemical industries operate, the concentration of these elements is much higher than the maximum permissible norm. Atmospheric air is monitored all over the world, including in Georgia. Monitoring is carried out using various devices. One of the sources of air pollution is vehicle emissions. During engine operation, large amounts of toxic gases are released, the most significant of which is CO. The main purpose of my work is to test the suitability of a cheap carbon monoxide detector for atmospheric analysis. To determine how accurate the detector is, its measurements are compared with data from online sources. In addition, carbon oxides (CO, CO2) and methane are determined using a Picaro 2401 CRDS analyzer. Research was conducted using two Alphasense sensors at SMART University | AtmoSim_LAB. One sensor delivers air to the device through an attached tube, so it is close to the operational data. The second sensor is in direct contact with the air, so it gives us a different reading. Analyzing the results, we determine the suitability of the sensor. The atmospheric air is constantly monitored.
