Design and Implementation of Agricultural Information Acquisition System Based on ZigBee and Qt

摘要

This paper introduces the design and implementation of agricultural products information collection system based on Qt and ZigBee platform. It consists of three subsystems mainly based in acquisition of images, temperature and humidity values which are passed to the regional gateway. The regional gateway is equipped with embedded Linux operating system and deployed Qt runtime library. The function of transmitting the static image of agricultural products and the temperature and humidity to the regional gateway through the ZigBee Wireless Sensor Network is realized, the pH value, electrical conductivity and light intensity of the growth environment of agricultural products were measured by using Qt library combined with sensor cluster, it can store, display and query the image, electrical conductivity and other parameters in the regional gateway.
