Air pollution is a major contributor to global warming, and efforts are being made to address this issue. Many metropolitan cities use Internet of Things (IoT) and communication technologies to better control environmental emissions and noise pollution. The goal is to reduce health-threatening risks and raise awareness about the effects of air pollution on human body.
One of the most important aspects of smart cities is their ability to provide a sustainable environment. Real-time smart city air monitoring of various environmental parameters allows policymakers to make data-driven infrastructure and policy planning decisions.
In the last year, there has been a surge in interest in air quality monitoring solutions in the context of smart cities. The market for non-regulatory devices is in its early stages and the number of market participants is increasing on a daily basis. According to Berg Insight- IoT analyst firm, the installed base of urban air quality monitoring devices surpassed 70,000 units in 2020 and is expected to grow at a CAGR of 34% to more than 300,000 units by 2025.
A smart city needs a variety of smart, robust, and compact environmental monitoring solutions capable of detecting different parameters of various air pollutants and weather conditions. All the data is collected and transmitted to a cloud server which can then be accessed, visualised, and analysed in the desired formats, such as reports, alerts, heat maps, and trend analysis. As a result, data-driven decisions for improved citizen health and a more sustainable environment are now possible.
Real-time Air Quality monitoring enables city administrators to send out advisory messages to residents to combat air pollution and protect their health and safety. One of the most important responsibilities of city administrators is to ensure that the elderly, children, and people with respiratory issues have a safe breathing environment. Furthermore, hotspot identification enables citizens to make informed decisions about where to live based on peak hour duration of air pollution.
Because air quality data is frequently used to make decisions that have direct implications for people’s health and well-being, the performance of air quality monitoring solutions is critical. Despite progress in this field, there is still no standardisation or certification for the air quality monitoring devices on the market. The government must intervene and implement various quality controls and checks in the manufacturing and implementation processes to ensure that all critical data is fully captured by these monitoring devices and transmitted to authorities in real time.
