| The determination of soil pH value is essential for improving the quality of soil environment. The laggard
conventional technology of pH value determination performs poorly in collecting real-time data and fails to integrate with
geographic informations of the testing field. Meanwhile, the device has simple functions and low flexibility. This paper
presented a remote soil pH value rapid detection system based on GPRS, functions of which included fast pH value
determination, real-time displaying, remote transmission. The pH value transducer transmited remote real-time data based
on GPRS technology, using Micro-controller STM32F103RBT6 as the core, which had high performance and low energy
consumption, using ZA-SOPH-A101 soil pH value sensor as its sensor module. According to the experiment on spot taken
in Jingyang Town, Xining City, Qinghai Province, the design was reasonable and worked well. It achieved fast soil pH value
determination and remote real-time data transmission with high accuracy, flexibility and reliability. The results indicate
that the pH value transducer meets the application requirements of fast soil pH determination. |
