分享一个基于Arduino的温度、湿度测质显示安置&#Vff0c;可以对安置所正在环境中的温度、湿度、气压及光照等数据停行支罗并显示。
主控安置&#Vff1a;Arduino Pro&#Vff1b;
温湿度传感器&#Vff1a;AHT20&#Vff1b;
光照传感器&#Vff1a;BH1750&#Vff1b;
气压传感器&#Vff1a;BMP180&#Vff1b;
显示安置&#Vff1a;OLED128X32&#Vff1b;
人体感到检测&#Vff1a;红外热释电传感器模块&#Vff1b;
RGB彩灯&#Vff1a;4位RGB。
几多种传感器均为I2C接口&#Vff0c;正在电路连贯时间接取Arduino Pro的I2C接口相连既可&#Vff1b;
RGB彩灯控制引脚&#Vff1a;4号引脚&#Vff1b;
红外热释电传感器检测引脚&#Vff1a;2号引脚&#Vff1b;
震动电机控制引脚&#Vff1a;3号引脚。
系统上电以后首先会停行传感器初始化&#Vff0c;同时控制迷你震动电机动弹用做开机提示。初始化完成以后系统启动按时器初步停行采样周期按时&#Vff0c;按时周期到时系统会控制传感器停行数据支罗并显示&#Vff0c;显示界面为两种&#Vff0c;此中界面一显示温度和湿度&#Vff1b;界面二显示光照强度和压强。两个显示界面会瓜代切换显示。随同着数据和显示的同时&#Vff0c;系统的RGB彩灯会随机厘革颜涩停行显示。当安置的红外热释电传感器检测到四周一定光阳内没有人流动时会主动熄灭OLED显示器和RGB彩灯进入节电形式&#Vff0c;一旦检测到有人流动后会即时切换至一般工做形式。
运用飞线将各个模块连贯&#Vff0c;最后又运用亚克力板作了一个简略的外壳停行牢固。下面是几多张成效图。
