草图上传后,打开“串行监视器”窗口以查看Arduino的输出。 在串行监视器上输出 代码说明: 草图首先包括DHT库。接下来,我们需要定义传感器的数据引脚连接到的Arduino引脚号,并创建一个DHT对象。因此,我们可以访问与库相关的特殊功能。 #include<dht.h>#define dataPin 8// Defines pin number to which the sensor i...
幸运的是，将DHT11或DHT22传感器连接到Arduino很简单。它们使用2.54mm间距的排针，因此您可以轻松地将...
必要时在 VDD 和 GND 之间并一个 100nF 的去耦电容。 本实验将传感器的 DATA 引脚连接到 Arduino 的 D2 口。 工作原理 DHT11 使用单一总线通信,即 DATA 引脚和单片机连接的线。总线总是处于空闲状态和通信状态这个2个状态之间。当单片机没有与 DHT11 交互时,总线处于空闲状态,在上拉电阻的作用下,处于高电平...
The Arduino microcontroller, being the processing unit of the system, gets the sensor's measured value and compares it with the set threshold. The results are: when the measured room temperature is less than the minimum of the threshold value; then, the microcontroller turns on the heater. If...
