Dark Sensor ( Light Sensor / Automatic Street Light ) : 4
Here is my new simple Electronics project about Automatic Street Light Control System or Dark Sensor. it is a simple and powerful concept , which uses transistor ( BC 547 NPN) as a switch to switch ON and OFF the street light system automatically . It automatically switches ON lights when the sunlight goes below the visible region of our eyes. ( e.g in evening after Sunset ). it automatically
Assessment of solar photovoltaic potentials on urban noise
From the complete set of 72,339 street-view images of the automatic noise barrier detection model, 20% (14,481 images) were selected from each of the three types of output datasets and used to test model accuracy. Among the 450 street-view images contained noise barriers, there are 316 images detected correctly and 134 images detected incorrectly.
