Sensors have a huge role in various industrial sectors in the development of smart and automated operations. Due to technological growth, different types of sensors are available in the industrial markets, which are mass-produced and reasonably priced. For instance, the temperature sensor, position sensor, pressure sensor, flow sensor, etc are increasingly used in the chemical industry 4.0. The main purpose of this work is to conduct a detailed review for analyzing the different types of sensors used in chemical plants. Also, it intends to investigate the issues, challenges, applications, and demands of the sensors used in smart industries. Typically, the primary advantages of using smart sensors are increased productivity gain, environment security, adaptability, high lifespan, etc. Moreover, this review investigates the major impacts of using smart sensor technology for industrial development and growth. According to the analysis, it is observed that smart sensors are now an essential part of integrated systems because they have an inbuilt module that supports communication and information exchange operations. For evaluation, the performance and efficiency of the smart sensor technology are validated by using various parameters.
