In the modern trends of computing, the exchange of external component is very essential, in order to make the programmer more comfortable for exchanging of data from one device to another. In the traditional days when ever we are going to insert the device in the running computer then, the system were unable to identify the device, so we need to restart the system each time whenever we are going to make any insertion or deletion of the peripheral as per our requirement (Social Networks of Things for Smart Homes Using Fuzzy Logic, 2018). There are many complex systems which do not fit into the precise categories of conventional set theory as i.e. based on the Boolean logic which works on either true or false i.e. 0 or 1. This paper is based on temperature sensing for hot swapping in device exchange using fuzzy logic .This paper thus presents a fuzzy logic based-temperature control system, which consists of a microcontroller, temperature sensor, Digital Converter, display interface circuit and output interface circuit (Advances in Fuzzy Systems on Real-Life Applications of Fuzzy Logic). It contains a design approach that uses fuzzy logic technique to achieve a controlled temperature output function. We have proposed the simulated voltage and temperature sensing graph also. It contains a graphical representation of different voltage fluctuation of USB ports in Matlab Software System.
