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。 在智能插座代码中,使用了ESPAsyncWebServer库创建Web服务器,server.on()函数注册不同的URL请求处理函数,根据请求将继电器打开或关闭,并发送相应的响应信息。
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: " + String(data.humidity, 1) + "%");//显示湿度...

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...
float humidity = sht31.readHumidity(); // 获取湿度值 String message = "Temperature: " + String(temperature) + " °C, Humidity: " + String(humidity) + " %"; // 拼接响应消息 server.send(200, "text/plain", message); // 返回响应消息 ...
String DoWork_Response(String SensorName,String SensorAction){ // 根据命令做控制 // 解析1-传感器sensor_all 命令GetData 返回所有的数据 if(SensorName=="sensor_all" && SensorAction=="GetData"){ // // 湿度 // float Humidity = dht.readHumidity(); // // 温度 // float Temperature = dht....

WebServer server(80); Then, we define the Adafruit_BME280 object named bme by setting it on the default I2C GPIO pins of ESP32. Adafruit_BME280 bme; The following three float variables will store the temperature, humidity and pressure readings acquired from the BME280 sensor. ...
