一个基于Arduino esp8266的无线温度&湿度读取器和与其链接的网关，具有NEXTION显示屏。

代码示例：

无线温度&湿度读取器：

#include #include "DHT.h"

#define DHTPIN 2
#define DHTTYPE DHT11

const char* ssid = "YOUR_SSID"; const char* password = "YOUR_PASSWORD"; const char* host = "192.168.X.XX"; // IP address of the gateway const int port = 8080;

DHT dht(DHTPIN, DHTTYPE);

void setup() { Serial.begin(115200); delay(10);

dht.begin(); WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected");
Serial.println("IP address: "); Serial.println(WiFi.localIP()); }

void loop() { float humidity = dht.readHumidity(); float temperature = dht.readTemperature(); if (isnan(humidity) || isnan(temperature)) { Serial.println("Failed to read from DHT sensor!"); return; } Serial.print("Humidity: "); Serial.print(humidity); Serial.print(" %\t"); Serial.print("Temperature: "); Serial.print(temperature); Serial.println(" *C");

WiFiClient client;

if (client.connect(host, port)) { Serial.println("Connected to gateway"); String temperatureData = String(temperature, 1); String humidityData = String(humidity, 1); client.print("Temperature: "); client.println(temperatureData); client.print("Humidity: "); client.println(humidityData); } else { Serial.println("Connection failed"); }

delay(5000); }
