Abstract:

Aiming at the application of WiFi technology in hospital in IOT, this article outlines the research background and the research status at home and abroad, after that

it introduces the relevant knowledge and theory of the Internet of Things and WiFi technology. IOT sensing terminal was designed based on WiFi technology and WiFi technology

into a small volume and lowcost embedded systems was introduced in the form of "ARM+WiFi SoC". The driver for WiFi chip on the physical layer and transplanted embedded TCP/IP

protocol stack on the network layer and the transport layer was developed, after that the upper layer application was also developed which could send acquisited data by Socket.

The system reaches the primary goal by testing.

Key words: WiFi, Internet of Things, LwIP, wireless sensor network
