void loop() { TempAndHumidity data = dhtSensor.getTempAndHumidity();//接受来自传感器的温度湿度数据,存入data变量 Serial.println("Temp: " + String(data.temperature, 2) + "°C");//开始通过串口显示变量的温度信息 Serial.println("Humidity:
the question is how a web client can access the web server hosted on the ESP32. When a device connects to a network, it is assigned an IP address. We can use this assigned IP address to refer to the device. For instance, when we connect the ESP32 to the...
在LED控制代码中,pinMode(ledPin, OUTPUT);将引脚设置为输出,digitalWrite(ledPin, HIGH);输出高电平点亮LED,delay(1000);实现闪烁的时间间隔。 在环境监测系统代码中,除了Wi-Fi连接部分,还使用了DHT库的函数dht.readTemperature()和dht.readHumidity()来读取传感器数据,通过isnan()函数判断数据读取是否成功。 在智...
