Applications of sensing technology for smart cities

The industrial revolution and rapid urbanization of human society have put a great strain on the resource consumption and environmental issues. The concept of a smart city with advanced technology can play a vital role to overcome these challenges and make life more sustainable and environment greener. Sensing technology has an intense impact in this regard starting from smart design of the infrastructure to autonomous control and monitoring of the overall system. This paper presents an overview of the state-of-the-art sensor technologies that can play a vital role in the design of a smart city. This paper is aimed to provide a brief review of sensing technology on some selected platforms such as environmental monitoring, agriculture, and food safety as well as in security. By discussing the emergence of the low-power smart sensor and the associated challenges, this paper attempts to provide a future research direction.
