Prototipe Sistem Pendeteksi Kualitas Udara Berbasis Arduino Uno

Abstract

Air Quality is one of the important factors that affect human health and the environment. To display measurement results in real time via LCD or serial monitor The method used in the Arduino Uno-Based air quality detector system is to utilize gas and/or air particle sensors connected to the Arduino microcontroller. The CO2 sensor showed very large data variations, with the highest value reaching 49.29 ppm and the lowest value only 4.04 ppm. This resulted in an average of 18.29 ppm and a high standard deviation of 20.85, indicating that the CO2 Concentration was quite significant during the measurement, the NO2 Sensor displayed very stable data. The average value of 4.06 ppm with a standard deviation of only 0.14, Indicates that this sensor has a a consistent response and the date is quite aacurate, and the CO sensor has an average value of 18.44 ppm, with moderate variations between 11.31-30.06 ppm. The standard deviation of 8.20 indicates a change in CO concentration in the environment, but is still within the limits measured by the sensor. Calculation statistics such a mean,median,range,and standard deviation help in understanding the stability, sensitivity, and accurancy of the sensor to the test environment.
