Agricultural Microclimate Observation Sensor: Based on Internet of Things by Using STM32 System

为实现分布式测量的农业小气候观测系统设计,需要设计一种体积小、成本相对较低的观测传感器。设计中应用STM32系统,采用现代电子设计技术及智能化的软硬件开发,实现传感器的设计制造。结果表明,应用STM32系统进行主控单元硬件设计,及STM32系统自带的标准库函数开发固化软件,不仅功能上能够满足要求,而且设计及生产成本均较低。设计完成的一体式传感器不仅能够更好地满足农业小气候观测需求,而且较集中控制方式的农业小气候观测系统有安装维护上的优势,其体积小,而且"全无线"设计,不会影响农事活动。基于物联网的智能化传感器设计为实现分布式测量打下了基础。

To realize the design of agricultural microclimate observation system with distributed measurement,it is necessary to design an observation sensor with small-size and relatively low-cost. Sensor design and manufacture were achieved by applying STM32 system and adopting modern electronic design technology and intelligent software and hardware development. The results showed that: the application of STM32 system for the main control unit hardware design and its own standard library function development firmware could not only meet the functional requirements, but also have low costs for design and production. The integrated sensor could serve the needs of agricultural microclimate observation, moreover, compared with the agricultural microclimate observation system with centralized control, it had the advantages of installation and maintenance, its small in size and"all wireless"design would not affect the agricultural activities. In conclusion, intelligent sensor design based on the Internet of Things lays a foundation for the distributed measurement.
