The development of IoT has increased the use of sensors in our daily lives. Individuals are making use of sensors on wearable items to monitor their vital signs and for many other purposes. As cities are focusing on becoming smarter and people use wearables more and more, the use of sensors in smart cities increases.

Public-Private Smart City Initiative in Kansas City

Smart cities bring along many improvement opportunities for cities, including the smart city initiative of Kansas City. In May 2016, Kansas City launched a public-private Smart City Initiative. The city launched its intelligent Sprint Wi-Fi network with the aim of it being the backbone of the city’s smart city framework. Moreover, the city also launched a 2.2 mile KC streetcar line through the city which connects the city’s iconic districts.

The Sprint Wi-Fi is aimed to enables different services for residents and visitors. The city wants to offer the following services along with it: public Wi-Fi, Sprint Wi-fi, Community Kiosks, Smart Lighting and Video. Each of the different services aims to serve a different purpose for both residents and visitors. With this initiative, the city is combining a communications network, wireless sensor technology, and intelligent data management. In the long term, this will allow the city to become more dynamic and efficient.

The Use of Sensors to Get Insight about Air Quality in Louisville

The city of Louisville is making use of sensors for a different purpose. The city has initiated a program that provides smart inhalers to asthmatics. By doing this they are able to collect data on the usage of the inhaler. In fact, they are able to correlate the data on the inhaler usage with EPA and sensor data on air quality. Moreover, this allows the city to explore the connection between asthma and air pollution.

To make this program possible, the city and philanthropic organizations have provided more than 1000 sensor equipped inhalers. In the long term, this should allow the city to create a map to show where air quality is triggering breathing problems.


These two examples show completely different uses of IoT technology in smart cities. Despite the fact that cities make use of data collected for different purposes, they all work towards the common goal of making the city more efficient. Cities are using the data collected to make their city smarter and better for the residents. Undoubtedly, the use of data collected for smart cities needs to be adapted for the different problems encountered in each city.
