这是一套基于单片机的温湿度测量系统，里边附有设计的原理图，pcb图，以及烧写程序代码（keil c51编写的）。温湿度传感器使用的是dht11，性价比高。该系统除了能显示温湿度以外，还能设置温湿度报警阈值。设计的pcb板，小巧，使用。这是本人的毕业设计，有实物为依据，具有可操作性。-This is a single-chip microcomputer-based measuring system of temperature and humidity inside with schematic design, pcb plans, as well as the programmer code (keil c51 prepared). Temperature and humidity sensors are used dht11, cost-effective. Except that the system can display temperature and humidity outside, but also set the temperature and humidity alarm threshold. Pcb board design, compact, use. This is my graduation project, there is the physical basis of operational.
