The PID regulation application allows users to transfer all the necessary data for the simplest system operation algorithm, which is the PID. The application can transmit the tuning parameters Kr, Ti and Tr of the regulator, which determine the type and quality of the transient process of the regulation system, as well as the dynamic properties of the object. The necessary transfer of information between devices in the system is carried out using the latest Bluetooth wireless technology. This system has all the necessary means for convenient and reliable control of devices based on Bluetooth communication.
