Design of android based Unmanned Surface Vehicles (USV) for oil spill monitoring [PDF]
IOP Conference Series: Materials Science and Engineering, 2021 Abstract In this research, a USV will be developed that can detect oil spills on the waters, so in the future it can overcome the problem of water pollution. To be able to determine the thickness of the oil on the water surface, TEMT6000 and LED sensors are used. The light intensity will be converted into ADC value by the TEMT6000 sensor.
