Development of a fuzzy controller for liquid level by using Raspberry pi and Internet of Things

In the control of industrial processes, liquid level control is one of the most basic but extremely important, PID controllers are used very often for the realization of control in these processes however, the rigor of obtaining a mathematical model that describe the plant to automate makes the adjustment of a controller of this type be very complicated, This article shows the development of a controller that uses an alternative method such as fuzzy logic which allows to perform intelligent control of this process, the controller is implemented in a Raspberry pi 3 in a remote location away from the plant to be controlled, the controller will communicate with the sensors and actuators of the plant with a Wi-Fi network so it will receive the measurements of the sensors and send the control instructions to relevant actuators.
