A Wireless Sensor Monitoring Node Based on Automatic Tracking Solar-powered Panel for Paddy Field Environment

Abstract

In order to realize the collection, management, visualization and uploading of real-time information in the paddy field, an information monitoring node based on automatic tracking solar-powered panel is presented in this paper. Firstly, the node consists of information collecting sensors, STM32 MCU, LCD, GPRS module, automatic tracking solar-powered module and monitoring interface. Secondly, data gathered from sensors can be displayed on the LCD and sent to the host computer interface. Moreover, host computer can also save the data packages to management server for examination and analysis. Finally, in the practical test, data are gathered every two hours. At non-test time, the node works in low-power mode to achieve rational use of electric energy.

Proposed System

In this paper, a wireless sensor monitoring node is adopted for paddy field environment. During monitoring, data are collected every two hours which lasts for five minutes every time. At non-test time, the node works in low-power mode to achieve rational use of electric energy. In order to minimize the error of data, Kalman filtering algorithm is applied to optimize real-time data. After processed by Kalman filtering, data are uploaded to remote monitoring software through GPRS module. In addition, automatic rotation function of solar panels is designed to achieve maximum efficiency in the power system of node. To solve these problems mentioned above, in this paper, a wireless sensor monitoring node is presented for paddy field environment. In this monitoring node, the more parameters such as moisture, temperature, pH, water level, light intensity are collected from the paddy field environment. After the processing by Kalman filtering algorithm, collected data are uploaded to remote monitoring software through GPRS module. Moreover, in this node, real-time data are displayed by LCD in collection part. In addition, the application of automatic rotation function of solar panels can make it possible to rotate solar panels following the sun to achieve the maximum efficiency. The results of experiment indicate that the node can achieve an accurate transmission of data and the power supply system can meet the demand of power.
