Abstract |
|
this paper proposes a power switching system based on op-amp and flip flop. The main objective is to design a shockproof power switching system for controlling power supply to electrical appliances via Light Dependent Resistor (LDR). This system consists of an op-amp, JK flip-flop, relay, Bi-polar Junction Transistor (BJT), Light Dependent Resistor (LDR). The system is designed to detect the change in the intensity of the light in the surroundings to perform the switching action. Several tests have been conducted to test and validate the proposed prototype in different environment. As conclusion, a shockproof switching system can be achieved reducing the chances of hazardous electrical shocks because of no physical contact with the switch. |
