Abstract

Oil pollution can destroy nature, aquatic life and crops. A simple approach for detecting oil pollution was developed using photodiode, microcontroller and light-emitting diode (LED). Our system was developed based on light absorption where the intensity of light that passed through a slick of oil was measured to detect the presence of oil in water. The analog value (intensity of light) from photodiode was converted to resistance value for further data processing. Experimental setup was conducted by varying distances (6 cm to 9 cm) from light source to photodiode, varying volumes (50 ml to 200 ml) and varying exposure time (1-6 hours). As the oil volumes increased, the average resistance values decreased. The system can be tested in irrigation canals, lakes or reservoirs used in agriculture. The system has the potential to assist farmers to detect oil pollution as a preliminary precaution before harming the plants.
