Applications that require level control are often meet in industry. In this paper a low cost application for level control in a tank using ardiuno mega 2560 was designed and developed. Level control is implemented by using Ultrasonic sensor HCSR04 and software Fuzzy with PID is applied to this system. This study includes level control using a PID controller and Fuzzy logic implemented on Arduino. The general purpose process is to ensure a desired level in a closed loop safety operational function. The developed hardware and software successfully implemented and tested with prototype system and the results are evaluated. The system is satisfactorily working with an accuracy of ± 0.03cm.
