We are continuing our research in Professor Profiri’s Dynamical Systems Lab. We are working on the air quality module for the Brooklyn Atlantis Project ARV. We successfully completed building the circuitry for air quality sensor array (measuring Nitrogen dioxide, Volatile Organic Compounds, and Ozone). We also finished the associated programming to convert the analog readings from the sensors to Ohms.

Next, we tested the sensors outdoors to establish a baseline sensor reading in ambient air. These measurements were used, in conjunction with logarithmic curves provided by the sensor datasheets, to determine values for the readings in parts per million (ppm) for each of the gases.

To enhance stability of the module, the circuits will be printed and sensors will be soldered to the circuit board. We also completed the assembly of a sensor array to collect relative humidity, temperature, and barometric pressure.
