Automatization of fog lamp based on LED sensor and photo dioda

Accidents due to misuse of fog lamps are traffic violations. To help minimize the misuse of fog lamps, the automatic fog lamp design is indispensable for car drivers to be applied directly to vehicles that still use manual fog lamps. This study aims to produce the design / prototype automatic fog lights with control LED and photo diode sensors that can work effectively, efficiently and economically and is able to function when the fog began to emerge through the simulation of CO₂ solid (dry ice). This research method uses experiments with implementation stages including (1) designing an automatic fog lamp circuit, (2) simulating the validity of the design, (3) refining the design until the final design is obtained, (4) product manufacturing, (5) product testing, (6) automatic fog lamp prototype. Design media using PCB (Printed Circuit Board). While the main components needed are batteries, switches, resistors, LEDs, photo diodes, transistors, relays, fog lamps, and cables. From the test results, the automatic fog lamp circuit design with the substitution of the light sensor is able to turn the fog lamp on and off automatically. The efficient distance for placing the LED and photo diode is 4.5 cm. Thus, the LED-based automatic fog lamp and photo diode can be used as an alternative to support the safety factor for vehicle users.
