Abstract

This paper gives the study on various sensors available in the market and their applications in different fields. As in our daily life there are various dependencies on the sensors rising from the beginning of the day start to the end of the day. there are various sensors manufactured based on the need and their application for example the elastic materials are used in fabricating and manufacturing the sensors used in the medical field for the measurement of parameters like Heart rate, PH factor, temperature so on. Whereas the sensors used in the food processing industries sensors are used to measure the parameters like temperature, humidity, etc but these sensors need not be flexible or the size is not a concern. Along with these there are many more applications of the sensors with the growing trend of smartness for eg. The upcoming smart cities depend on these sensors where each individual house would be equipped with various and different types of sensors. The sensed data from these sensors needed to be communicated to the concerned people hence to do this monitoring system with embedded systems for analysis use of portable sensors play a vital role in monitoring the various parameters need to be measured and corrected, theses sensors are fault tolerant and has high accuracy to the senses data and indicates the malfunctioning of the body parts. Here we are classifying the sensors and the designs based on the materials used for the particular applications and their design and here the communication of the sensed data is done using the WSN. These sensors are fault tolerant, accurate, and reliable.
