IOT-Based Pollution and Air Quality Monitoring Equipment with ESP-8266

Abstract

Modern industry urgently needs air quality detectors, which are used to detect air pollutants, such as; CO, CO2, SO2, and NO2, which are not good for the health of living beings and the environment. In this study, we created a tool that can monitor the gas and provide results in PPM (parts per million). Sensors will collect parameter data and environmental data will be output to the server.The conclusions as follows: first, The design of the air pollution detection device uses the MQ-135 gas sensor with IOT-based technology to detect CO2, SO2, and NO2 gases. The input from the gas sensor is processed through the ESP-8266, will produce an air quality index output, thus displaying the index in various places/locations, which will be displayed on the monitor, and, the second is The latest implementation of this air pollution detection tool using the MQ-135 can identify hazardous air levels of CO2, SO2, and NO2 gases, which then provide indications and information to android application users and computers, with an air quality index/value.

Development of an Early Warning System Using Social Media for Flood Disaster

“…Conducting research involves testing and validating the system's effectiveness in realworld scenarios, comparing results to established methods, and analyzing collected data [32]. The prototype includes an ultrasonic sensor that measures distance and transmits data to the ESP8266 microcontroller, which converts and uploads it to ThingSpeak for logging and analysis [33], [34]. Additional sensors such as temperature, humidity, or atmospheric pressure sensors can be used to…”
