⑴ 基于单片机的温湿度检测系统设计
<<pic单片机应用系统开发典型实例〉〉有差不多的例子,不过 是数码显示,不是液晶显示。液晶程序上网上找就行啊,www.pic16.com上有很多程序,或许有现成的。
⑵ STC单片机温湿度监测系统所需元件清单
温控器历誉 74HC595D
可控硅 BT137
光藕 MOC3063
放大器 OP07
继电器 OJESS-124HM
AD转换消烂笑拿含器 ADS1110(选用件)
⑶ 基于单片机的温湿度检测系统主程序流程图,温、湿度检测程序流程图,报警程序流程图,传感器是dht11
图4.1 系统主程序流程图
图4.2按键子程序流程图
⑷ 基于单片机的温度控制系统
加热部件可以在淘宝上买个
usb
5v
加热片,usb供电的电流不会超过
500ma,
控制可以用单片机脚控制一个
c8050三极管控制加热片的通断电。
⑸ 想用单片机做温湿度监控与反馈系统
这个本身没什么难度,最主要的是驱动dht11,也就是模拟单总线时序,软件模拟要好好设置,也可以用状态机完成。
⑹ 温湿度传感器为什么要接单片机的中断口才可以监测
因为单片机在温湿度传感器中是以最小系统作为核心控制电路的,同时控制传感器采集的温湿度的转换。
单片机是一种集成电路芯片,是采用超大规模集成电路技术把具有数据处理能力的中央处理器CPU、随机存储器RAM、只读存储器ROM、多种I/O口和中断系统、定时器/计数器等功能(可能还包括显示驱动电路、脉宽调制电路、模拟多路转换器、A/D转换器等电路)集成到一块硅片上构成的一个小而完善的微型计算机系统,在工业控制领域广泛应用。
⑺ 基于单片机温湿度测量系统(摘要翻译)
Along with the humiture examination system's widespread utilization, the different profession and the domain have the various requirement and the standard to the humiture examination. This design mainly uses in the ordinary indoor humiture survey. Uses the DS2438, HIH3605B integration chip to take the humiture sensor. In the article has analyzed the humiture survey principle of work and the process, proposed the humiture examination system design's overall plan, has carried on the plan proof to each submole design and compares. The hardware design uses protel the 99se software, has completed the monolithic integrated circuit smallest system, the LCD display circuit, sensor's schematic diagram and the PCB chart. The software design uses Keil uVision2, has completed the program mole each mole design programming, has realized to the humiture signal processing process programming and the debugging. This measurement system humidity measuring range 0%~100%, resolution ±2%; Temperature survey scope - 40~+125℃, resolution ±0.5℃. Can meet the daily life humiture survey requirements.
