Air pollution is one of the environmental issues that have been often discussed. The fast-growing population and urbanization result in the population concentrated in certain areas. Heavy transportation may lead to poor air quality and inhaling pollutants for a long time also causes damages in human health. A traditional air quality monitoring method is to build air quality monitoring stations, but this method is expensive and provides low resolution sensing data. In this paper an industry based quality air monitoring system based on the wireless sensor network technology and integrated with the ZigBee wireless technology is being implemented. The system consists of a sensor node and a back-end platform controlled by the embedded data acquisition system through which sensing data can be displayed. The data can be stored inside a computer based application and could be accessible to those people having the application. This system can also be deployed to the main roads and automobile...

WSN Based Air Pollution Monitoring System2013 •
The paper presents Wireless sensor network system used to monitor and control the air quality in Nagpur city, India. Environmental air pollution monitoring system that measures, RSPM (Respirable Suspended Particulate Matter), NO x , and SO 2 are proposed. The traditional air quality monitoring system, controlled by the Pollution Control Department, is extremely expensive. Analytical measuring equipment is costly, time and power consuming, and can seldom be used for air quality reporting in real time. Wireless Sensor Networks are a new and very challenging research field for embedded system design automation, as their design must enforce stringent constraints in terms of power and cost. Wireless Sensor Network is a fast evolving technology having a number of potential applications in various domains of daily-life, such as structural and environmental monitoring, medicine, military surveillance, condition based maintenance etc. A WSN is composed of a large number of sensor nodes that are usually deployed either inside a region of interest or very close to it. WSN nodes are low-power embedded devices consisting of processing and storage components (a processor connected to a RAM and/or flash memory) combined with wireless RF transceiver and some sensors/actuators. The proposed system makes use of an Air Quality Index (AQI) which is presently in use. Several sensor nodes, which measures pollutants information, were uniformly deployed in the networks to create sensing phenomena. The simulation results consist of the scenario generated and x and y coordinates of the nodes from the gateway by using Network Simulator (NS-2.33). For better power management we used low power strategies and hierarchical routing protocol in wireless air pollution system and caused the motes to sleep during idle time.
Wireless Sensor Network For Real Time Air Quality Monitoring
Wireless Sensor Network For Real Time Air Quality Monitoring2019 •
DIT Dar es Salaam campus environment is located at the centre of Dar es Salaam city. Moreover it is located at the middle of highly congested roads; Morogoro road, Bibi Titi Mohamed and Aly Khan Road. This being the case the environment of DIT is likely to be highly subjected to poor air quality mainly due to the effect of green gases emitted by moving motor vehicles. Poor air quality at DIT is also contributed by construction activities of the nearby buildings. Hence, the lives of people at DIT could be vastly exposed to some dangerous diseases like lung cancer and Tuberculosis by inhaling polluted air. In this project report, WIRELESS SENSOR NETWORK FOR REAL TIME AIR QUALITY MONITORING is proposed at DIT Dar es Salaam campus. In this proposed system different sensing nodes will be placed at different places within DIT campus and there will be a single network coordinator/gateway. Using this proposed system changes in air will be measured in real time and the resulting data will be uploaded to a cloud server. By using an android application individuals will be able to access this real time air quality information mapped into DIT Google map. The proposed system has been tested and from the results it has been observed that; during busy hours there is a higher content of Carbon monoxide (CO) and Nitrogen dioxide (NO2) in the areas near Morogoro road compared to any other area in the campus. Moreover, during daytime areas around Block III, Block IV and the football ground have observed to have higher contents of PM10, PM2.5 and Carbon dioxide (CO2) compared to any other area of the institute’s campus. Practical implementation of the proposed system will enable individuals at DIT community to have access of air quality information at their fingertips. Moreover the authority will have a proper record of air quality data which can be used in further air quality studies and researches. Furthermore, this system can be extended to a broader network with the purpose of monitoring air quality in larger areas.

Many changes of air characteristics can be caused by air pollution. Indoor air pollution can cause harmful results. Welding for example may generate harmful pollutants like fume. A direct exposure to pollutant gases may increase the health risks also these harmful gases may threat the environment. For these reasons air pollution is an important issue and attention must be taken to reduce its risks for environment and health. An air pollution avoidance and monitoring system using wireless sensor network is introduced in this paper to monitor and avoid the indoor air pollution. A prototype of proposed system contains set of gas sensors (CO, LPG, NO2, NH3, CH4, SO2, Butane, Propane and Ethanol) which are organized in the wireless sensor network infrastructure. The gas sensors are controlled by microcontroller and the main server which is represented by raspberry pi3 contains the SQL database to support real time monitoring strategies. A web interface is used to monitor the entire system in forms of charts and numbers also fans and relays are used in case of high level of gases concentration when the level of CO gas is above the threshold an email is automatically sent to the department of civil defense. Wi-Fi technology is used to connect microcontrollers with server and the communication is achieved by using Message Queuing Telemetry Transport Protocol (MQTT). Authentication and substitution cryptography are used to introduce a kind of security for the system.

Environmental conditions have a major impact on our well-being, comfort and productivity. Present state of the air quality control in almost all manufacturing industries in our country is based on taking samples one or few times a day, which means that there is no information about time distribution of polluted materials intensity during day. This paper proposes an industrial air pollution monitoring system based on wireless sensor network system that enables sensor data to be delivered within time constraints so that appropriate observations can be made or actions taken. Obtaining these accurate real-time results in-situ allows regulatory agency to take necessary action whenever pollution occurs. The analysis focuses on six substances, known as criteria air pollutants – ozone, particulate matter, sulphur oxides, nitrogen oxides, carbon monoxide, and lead. The sensors self-organize themselves in a radio network using a routing algorithm, monitor the area to measure the gas levels in...
