Let's Interface the Sharp GP2Y1014AU0F Sensor with Arduino to estimate the Dust Density in Air.

About Project

Sharp's GP2Y1014AU0F is basically a six-pin analog output optical air quality analyzer that is specifically outlined to sense dust particles in the air. It operates on the principle of laser scattering. When air involving dust particles enters into the specific sensor chamber, the dust particles disperse the IR LED light towards the photodetector. The intensity of the scattered light relies on the dust particles. The higher the dust particles in the air, the significant the intensity of light.

Organic Light-Emitting Diodes is a self-light-emitting technology, designed by placing a series of organic thin films in between two conductors. A bright light is generated when an electric current is implemented in these films. OLEDs are utilizing the same technology as televisions, but have fewer pixels than most TVs.

While doing soldering, make sure your solder wires should be at a sufficient distance from each other.
