An Environmental Air Pollution Monitoring System for monitoring the concentrations of major air pollutant gases has been designed, developed, and tested complying with the Zigbee standard. This system measures concentrations of gases such as CO, NO2 and SO2, and using semiconductor sensors. The hardware unit integrates a single-chip microcontroller, air pollution sensors array, a Zigbee Modem and a Global Positioning System Module (GPS-Module). The Central-Server is a high-end personal computer application server with Internet connectivity. The hardware unit gathers air pollutants levels (CO, NO2, and SO2), and packs them in a frame with the GPS physical location, time, and date. The frame is subsequently uploaded to the ZigbeeModem and transmitted to the Central-Server via zigbee network. The Central-Server is interfaced to Google Maps to display the location of hardware unit. The system was successfully tested in the city of Nagpur, India. Keywords-Air pollution Monitoring; Zigbee.
See Full PDF See Full PDFSensor networks are presently an active research area mainly due to the potency of their applications. This paper is proposed to implement wireless sensor networks based Environmental air pollution monitoring. RSPM (Respirable Suspended Participate Matter), carbon dioxide, carbon monoxide Nitrogen Dioxode (NO2) and sulfur dioxide (SO2) are monitored because these gases decide the level of pollution. We have used MQ-7, MQ-2 sensors to monitor the Carbon Dioxide and Carbon Monoxide levels in the atmosphere. The ARM processor (LPC2148) is used as the prominent platform for interfacing those sensors and processing the sensed data wirelessly through Zigbee modules (Tarang F4). The data received from the sensor device is simultaneously stored in a system for a future reference in the levels of contamination. The information in the system is stored via a .Net application enabling the user to access the data whenever required. With the help of this data, proper precautions can be taken to minimize the pollution levels in the air to make human life sustainable.

The design and development of a ZigBee-based monitoring system is a key component of this paper. The proposed monitoring system is in need of the hour in metro cities of dense population countries like India. The carbon emission from industries and a large number of vehicles in metro cities in India demand low-cost, low-power, real-time distributed monitoring systems. We have chosen Pune city in Maharashtra, India for the implementation of the monitoring system due to the frequent changes in weather and rainfall conditions observed in 2019. Our main objective is to provide real-time monitoring of air quality at distributed locations by using ZigBee-based distributed real-time air quality monitoring. The extra efforts that we have done here is to observe and monitor Pollution levels after and before rainfall in Pune City, India. The highlight of this paper is the establishment of the interrelation of air pollution and rainfall and the comparisons of environmental monitoring Keywords: - ZigBee, AQI, rainfall monitoring, , air quality, weather monitoring, Pune India weather, GSM, GPRS, environment monitoring, Wireless sensor networks, MQ135.

Internet of Things enables the physical devices to embedded with software, sensors and network connectivity to sense, collect and exchange data for the direct integration of physical world into computer based systems. In this domain, a Wireless sensor network is deployed for air quality monitoring system. The objective of this paper is to investigate the concentration measure of the air pollution around the city and provide the quality level of the air to the end user. A sensor node includes a microcontroller for a data analysis, Global Positioning System device for location access and XBee transceiver to communicate with a server. Each sensor node is established at public spaces like traffic signal and periodic sensing and transmission is done. Users who use Smartphone with a special android application connect to the server through the internet and select a city and location the place listed. Through this the level of air pollution in the place is displayed.

Air pollution has significant influence on the concentration of constituents in the atmosphere leading to effects like global warming and acid rains. To avoid such adverse imbalances in the nature, an air pollution monitoring system is utmost important. This paper attempts to develop an effective solution for pollution monitoring using wireless sensor networks (WSN) on a real time basis namely real time wireless air pollution monitoring system. Commercially available discrete gas sensors for sensing concentration of gases like CO and CO2 are calibrated using appropriate calibration technologies.These pre-calibrated gas sensors are then integrated with the wireless sensor motes for field deployment at the campus and the Coimbatore city using multi hop data aggregation algorithm. A light weight middleware and a web interface to view the live pollution data in the form of numbers and charts from the test beds was developed and made available from anywhere on the internet Other parameters like temperature and humidity were also sensed along with gas concentrations to enable data analysis through data fusion techniques. Experimentation carried out using the developed wireless air pollution monitoring system under different physical conditions show that the system collects reliable source of real time fine-grain pollution data.

This study focuses on enhancing sensor technology and shrinking the size of sensors utilized in monitoring the quality of atmospheric air. With the escalating concerns over air pollution due to factors such as increased vehicular traffic, industrialization, and urbanization, there is a pressing need for effective monitoring solutions. The innovation at the core of this study involves implementing IoT technology via a Wi-Fi module interfaced with a gas sensor, facilitated by an Arduino UNO microcontroller. Specifically, the study proposes the utilization of the MQ 135 Air Quality Monitoring Gas Sensor for measuring air pollutant concentrations. The setup primarily comprises an Arduino UNO board integrated with an ESP8266 module for IoT connectivity. This IoT which depends on Air Quality Monitoring System is designed to monitor the air quality via a web server using the ESP8266 Wi-Fi device. Additionally, it is equipped to trigger an alarm when air quality deteriorates to a certain level, indicating the presence of harmful gases like CO2. The system displays air quality depends in Parts Per Million categorizing it into Fresh Air, Poor Air, or Danger Air, allowing users to monitor the air condition status effectively.
