A multi-functional crop intelligent monitoring system, including internet and Arduino micro-controllers, function to upload humiture, soil moisture, light intensity, PM2.5, harmful gas and other real time data. The system's other functions include automatic watering of crops when the humidity data exceeds warning levels, broadcasting the condition of crops by Microblog, remotely controlling the watering and lighting by web and WeChat and remote video monitoring. Data collection of sensor data is conducted by Arduino UNO micro-controller and the data is uploaded real time into the internet by HLK-RM04 WiFi module. Software functions of the system include real time charts by Websocket, JavaScript in PC and mobile internet, and concurrently, the implementation of WeChat control and Microblog broadcast through Tencent micro channel public platform and Sina Microblog.

ACFM is a kind of non-destructive testing technique based on electromagnetic induction principle, whose operation is so simple that can rapidly find surface and near surface defects. However, the interface software of ACFM instrument produced at home needed to run on a computer or laptop for further data analysis and waveform display, which was no convenient for special occasions, such as testing of pressure vessel, large entertainment equipment. In order to develop the advantages of the real-time detection of ACFM, this paper proposes an ACFM interface software based on Android, which can be loaded in portable devices running on Android system and can be operated through the touch screen .Just open Wifi to connect wireless probe can start testing.
