SISTEM PENILAIAN KUALITAS UDARA PERKOTAAN

Urban air quality must be closely monitored, especially when it comes to human health. Chemical pollutants, physical pollutants, and biological pollutants are the causes of urban air quality problems, which have detrimental effects on health and comfort. Therefore, with the advancement of technology, a system has
been designed to monitor air quality, CO2, CO, NH4, temperature, and humidity. The levels of these gases can be measured using an MQ-135 sensor to detect CO2, CO, and NH4 gases, a DHT11 sensor to detect temperature and humidity, and the NodeMCU ESP8266 as the microcontroller. The readings from these sensors can be categorized into good, moderate, and poor air quality levels using fuzzy logic in urban air quality decision-making. The gas sensor readings will also be transmitted in real-time to an Android smartphone using the ESP8266 Wi-Fi module and the Blynk software to display the sensor readings. The development stages include adding fuzzy logic, implementing Blynk software for
monitoring. With this device, it is hoped that the public will become more aware of the air quality in their surroundings, thereby minimizing the increase of hazardous gases in their environment
