Design and Implementation of Data Acquisition System for Agricultural Meteorological IOT

Abstract

A data acquisition system for agricultural meteorological IOT based on STM32 processor is proposed in this paper, including power supply module, sensor data acquisition module, GPS positioning module, GPRS module, external FLASH memory and LCD screen. Experiments and demonstrations were conducted in 56 cities and counties of Anhui Province. The results showed that the monitoring stations and software platforms were operating stably; the collected data were complete and no packet loss were found; the trend of data changing was consistent with the local agro-meteorological information, and it has a small deviation to the test results that using laboratory-standard instruments. The system can accurately monitor the agricultural meteorological conditions at the agricultural production site.
