Abstract: In the rapid development of Internet and mobile terminals today, greenhouse traditional access to
environmental information obviously should follow the footsteps of Internet+era, namely access to data through the
mobile terminal to replace the traditional way, this satisfies the user needs for efficient, fast and so on. This
paper presents a system based on Android platform realizing information acquisition and remote display. Android
platform is used to achieve the greenhouse temperature information collection and upload to the remote server.
Users through the Android client program or browser to achieve the temperature of the information. It greatly
improves the convenience of access to temperature information, users can do anytime, anywhere real-time. The
system’s workflow is as follows. First, embedded Android platform through JNI (Java Native Interface) call to
read the external temperature sensor data. Upload the collected data to the LAMP (Linux Apache MySQL PHP)
server via the Internet. Then, run the Android client or browser to access the Web page. Through the Internet
from the server to obtain data to the user. After running the test program proves that the system is stable and has
a good user interaction effect. When the information collection terminal is under poor network state, data upload
program is optimized to achieve the continual transfer after the network recovery.
