Chapter 1Introduction1.1 origin and importance of the project Nowadays, technology has been developed as a power in which we notice that in the community, such as public gardens. When the sun set. Power walk will be opened. When the sun goes down. Power walk, it will close itself and observed daily life in schools have noticed that the school has a college and have the ROI classes so there is a continuous supply of electricity usage and cannot control off-power to be opened so we had the idea to solve the problem of electricity supply in the school example build artifacts "Auto dark sensor system."1.2 objectives.1.2.1 there is knowledge and understanding about the principles and system of the electrical circuit of Auto dark sensor system.1.2.2 the electronic technology can be used to control lighting systems. In the dark of the Auto sensor system electrical circuit.

Introduction 1.1 Background and importance of the project in the current technology has developed dramatically. In terms of power We then noticed in the community, such as a park. When sunset Electrical path can be opened manually. As the sun rises Following the passage of electricity, it turns off by itself. And from observations of everyday life in schools was noted. Roi College with area school And many classrooms The use of electric consumption. And can not be controlled - off electricity throughout it. We have an idea to solve the problem of electricity consumption in schools to create inventions "Dark Auto sensor System" 1.2 Objectives 1.2.1. Understand the basic concepts. And the electrical circuits of the Dark Auto sensor System 1.2.2 of electronic technology can be used to control lighting systems. In the circuit's Auto dark sensor system.

1.1 introduction history and significance of the project work

.Currently, there is the development of the technology very much, in terms of electricity, which we นั้นก็ได้ notice in the community, such as at the park. When the sun set, electric path can be opened.Electrical path will close. From the observation of everyday life and in the school notice The school has a wide area, et college classrooms and many have electricity end injurious.We have a concept to solve the problem of electricity supply in schools to create artifacts. "Auto dark sensor system"
