Ir TV Remote Based Speed Control of Single Phase Ac Motor

Abstract

This article outlines the development and implementation of a speed control system for a single-phase AC motor using an infrared receiver module based on PIC microcontroller. The proposed speed control method allows users to remotely operate the AC motor. In this system, volume (+ /-) button on the remote control can e utilized to adjust the speed of the AC motor. When a push button on the remote controller is pressed, the infrared light-emitting diode transmits the signal that is received by the receiver in the infrared sensor module interfaced with micro-controller. Subsequently, the micro-controller interprets this signal, enabling control over the firing angle of the AC voltage controller. As a result, the AC motor operates at the desired speed as commanded by the remote controller.
