A kind of Wi-Fi technology-based environmental monitoring system is realized.It can accurately obtain temperature

light sensor parameter and RSSI value

establish connection with the server

by wireless mode and server can real-time receive sensing datas and complete real-time targets monitoring and other related results display.While

if the system monitors one parameter of monitoring area such as temperature or RSSI beyond user’s demands

the buzzer will alarm and screen will display the corresponding parameter and its value for user to adjust.Repeat experiments several times

it shows that the system can monitor environmental area real-time

correctly and stably

and possess good practical value and application prospect.
