基于单片机的雨量检测系统设计

针对洪涝灾害问题,开展雨量自动检测系统设计,避免洪水对人们造成生命财产的损失.以STM３２F１０３ 型低功耗单片机为核心,利用 FC-３７ 雨滴传感器、 NRF２４L０１ 无线收发模块以及 OLED 显示屏等实现雨量无线检测.该系统分为主机和从机 ２ 个控制部分,从机主要包括雨量检测模块和 OLED 显示模块,通过无线模块将采集到的数据发送到主机;主机一方面检测自身环境下的雨量信息,另一方面由无线模块接收从机雨量信息并发送给 OLED 显示屏显示出来.结合电路原理图进行硬件设计,测试结果表明,该设计实现了主机和从机对雨量的实时检测功能.

Design of Rainfall Measuring System Based on Single Chip Microcomputer

Aiming at the problem of flood disaster , automatic rainfall monitoring system is proposed to avoid the loss of people ’s life and property caused by flood．Taking the rainfall low power microcontroller STM３２F１０３ as the core , combined with the FC-３７rain sensor , NRF２４L０１ wireless transceiver module and OLED display screen , a rain wireless detection system is designed．The design is divided into two control parts : the host and the slave , the slave from the machine part mainly includes the rain detection module and the OLED display module , through the wireless module to send the collected data to the host ; the host section detects the rainfall information in its environment on the one hand , on the other hand , the wireless module receives the rainfall information from the machine and sends it to the OLED display．Combined with the electrical schematic diagram for hardware design , the test results show that the design realizes the real-time monitoring of rainfall by the host and slave．
