*The United States has made great progress since 1970 in cleaning the air, and 15 November 1990 marked a milestone in Clean Air Act history with the signing of the 1990 Amendments. These amendments set the stage for protecting the ozone layer, reducing acid rain and toxic pollutants, and improving air quality and visibility. Measuring air quality and weather conditions is increasingly important for those involved in the construction of new infrastructure. Whether building residential units, roads, bridges or any other piece of infrastructure, activities such as land clearing, running diesel engines, demolitions, and burning can Air and weather monitoring enables safe construction In city environments, every square metre costs. Overseas, in an effort to support the dietary needs of the often colossal populations that inhabit their limited spaces, urban farmers use unconventional infrastructure such as skyscrapers and rooftops to harvest crops in and atop vertical farms. To effectively grow within such structures — which can be significantly less accessible than the conventional rural landscapes where most traditional all adversely impact air quality, placing the health of the general population (particularly those with respiratory diseases) at risk. Assessing atmospheric conditions, such as wind speed and direction, is also important to predict the risk of such pollution spreading to adjoining territories. Research has demonstrated that asthmatics are 40% more likely to suffer acute asthma attacks on high pollution days than on days with good air quality. Whether mandated to comply with legislation, such as the EPA Clean Air Act, or proactively initiated by companies seeking to minimise their environmental footprint, measuring gaseous air pollutants such as nitrogen dioxide, sulphur dioxide, carbon monoxide, ozone, and particulate matter helps reduce pollution for the benefit of all a city’s inhabitants.* Smart sensors and special IoT communication networks are the two key components of any smart city project. Initiatives to implement the technologies mentioned here, such as the London Air Quality Network (which may involve a significant open-source component) and San Francisco’s ongoing efforts to develop a smart sewer network, show that IoT- supported sensor technology can have a far-reaching impact on the lives of urban citizens around the world. u Smart agriculture farms exist — such farmers need real-time access to vital agricultural parameters such as evapotranspiration rates, soil moisture saturation, and groundwater conditions. Smart, IoT-powered sensors allow these agricultural pioneers 24/7 access to this vital information, no matter where in the world (or city) they are located. In this regard, in the US, Chicago is quickly emerging as America’s urban agriculture capital with 820 urban farms now in operation. monitoring uses advanced sensing technology to analyse and interpret raw measurement data to improve systemwide power-quality delivery. This ensures that urban infrastructure systems requiring a consistent supply of high-voltage power, such as an electrified light rail, suffer less damage (such as from overheating) and component failures during their useful lifespan.
