Automatic method to display sooty smoke degree because is variable according to car sooty smoke density

摘要

PURPOSE: A method for indicating a smoke degree through automatic variation according to smoke density of a vehicle is provided to properly execute ventilation according to smoke density of the vehicle. CONSTITUTION: A method for indicating a smoke degree through automatic variation according to smoke density of a vehicle comprises steps of sending a smoke-sensing signal to a CPU(Central Processing Unit) from an arithmetic unit after connecting input power; sending the smoke-sensing signal to a sensor from the CPU and sorting on and off; receiving a sorted signal and sending the sorted signal to a non-contacting switch through the CPU; and operating the non-contacting switch and operating an LED(Light-Emitting Diode) to indicate smoke density.
