Alat Ukur Densitas Debu di Udara Berbasis Mikrokontroler

Abstract

Had created a dust density of measuring the instrument by using GP2Y1010AU0F Optical Dust Sensor-based on the microcontroller ATMega16, wherein the sensor detects the density of dust in the simulation room measuring 15 cm x15 cm and in the room , there is a PC fan that serves to absorb and remove dust. The principle works is the light reflected on the surface of the particles pass through the overall, then by the photodiode was converted into a voltage. Voltage should be strengthened to be able to read the changes. The output of the sensor is an analog voltage that is proportional to the measured dust density, the sensitivity 0.5V/0.1mg/m3. The program is executed by the microcontroller to provide an output that will be displayed on the LCD in digital numbers.
