Title Design and Implementation of the experimental platform for the Internet of thing
Abstract
With the development of science and technology, Internet of things has become following the computer, Internet and mobile communication network of the world information industry the third wave. To deepen students understanding of the concept of the Internet of things and the network technology base master and strengthen networking technology teaching has become a pressing issue. Therefore, composed of light sensors, temperature and humidity sensors, CC2430 chip and MCU simple sensor network is designed, which is network experimental platform. Including the hardware circuit design, software design of MCU, the realization of the detection of light intensity and air temperature and humidity, and can carry out wireless communication with the host computer. This device can be applied to the students' understanding of basic concepts for networking and learning for application in the design of wireless sensor networks.
