摘要
以ARM Cortex-M3作为控制核心,采用BH1750FVI作为光强度传感器,通过2.4寸TFT液晶显示器进行信息显示,设计实现了光照强度监测系统。系统主要由单片机模块、光照强度采集模块、报警模块、语音播报模块和液晶显示模块组成。测试结果表明:系统稳定、可靠、性能高,能够实现0~65 535 lx范围内光照强度的准确监测,适用于温室大棚、家禽场等环境下光强的实时监测。
A light intensity monitoring system is designed and implemented, where ARM Cortex-M3 is used as the control core, BH1750 FVI is used as the light intensity sensor, and a 2.4'' TFT LCD for information display. This system consists of single chip computer module, light intensity collection module, alarm module, voice broadcasting module and LCD module. The test results show that the system is stable, reliable, and high-performance, enabling accurate monitoring of light intensity in the range(0-65535 lx). It is suitable for real-time monitoring of light intensity in greenhouses, poultry farms and other environments.
