基于单片机的雨量检测系统设计

Design of Rainfall Measuring System Based on Single Chip Microcomputer

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。

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 37 rain 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.
