查找所需要的程序库 安装DHT sensor library 2. 编写相关程序 2.1. 引入头文件 #include<DHT.h>#include<DHT_U.h> 2.2. 创建DHT对象 DHT对象创建的函数需要两个参数,一个是用于获取数据的引脚号,一个是传感器的类型(可选DHT11、DHT21、DHT22)。 所以在创建对象之前,通过宏定义的方式对于所需要的两个参数进...
使用这个模块是非常容易的，因为其由Arduino提供的库。// Init the DS3231 using the hardware interface...
const int DHT_PIN = 15; //定义一个整形变量,目的是使用GPIO-15来接收来自传感器的数据 DHTesp dhtSensor; //定义一个DHT传感器 //arduino里的setup函数,执行一次 void setup() { Serial.begin(115200); //串口的速率 dhtSensor.setup(DHT_PIN, DHTesp::DHT11);//把DHT11与gpio第15号数字引脚关联。
I'm thrilled to announce the release of the DHT11 Sensor Library v2.1.0 for Arduino. This version introduces several enhancements, optimizations, and a significant hotfix aimed at improving functionality and user experience. Importantly, this release is backward compatible with previous versions, ensur...
