Je travaille actuellement pour mon projet final, mais j'ai un problème. Je veux envoyer mes données de capteur à la base de données MySQL en utilisant XAMPP et phpMyAdmin. J'ai utilisé NodeMCU pour la connexion WiFi. Mais je suis incapable d'envoyer la valeur.Sauvegarder les données de NodeMCU vers PHP MySQL
Voici le code complet de mon travail.
#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>
#include <WiFiEsp.h>
#include <WiFiEspClient.h>
// Sensor 1
int sensorPin1 = 5;
int ledPin1 = 13;
// Sensor 2
int sensorPin2 = 4;
int ledPin2 = 12;
// Sensor 3
int sensorPin3 = 0;
int ledPin3 = 14;
//Wifi Connection
const char* ssid = "xxxxxx";
const char* password = "xxxxx";
const char* web = "192.168.1.69";
int status = WL_IDLE_STATUS;
WiFiServer server(80);
//Initialize the Wifi werver library
WiFiClient client;
void setup(void) {
//start serial port
Serial.begin(9600);
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
pinMode(ledPin3, OUTPUT);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.print("This is your ip address: ");
Serial.print(WiFi.localIP());
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.println(request);
client.flush(); // Match the request
if (client.connect(web, 80)) {
int sensor = digitalRead(sensorPin1);
int sensor1 = digitalRead(sensorPin2);
int sensor2 = digitalRead(sensorPin3);
//connect to the server (your computer or web page)
Serial.println("--> connection ok\n");
client.print("POST /smart_parking/sensor.php?"); //This
client.print("sensor=");
client.print(sensor);
client.print("&sensor1=");
client.print(sensor1);
client.print("&sensor2=");
client.print(sensor2);
// client.print("sensor="); //This
// client.print("100");
client.println(" HTTP/1.1");
client.print("Host: ");
client.println(web);
client.println("Connection: close"); //Part of the GET request telling the server that we are over transmitting the message
client.println();//empty line
client.println(); //empty line
client.stop(); //Closing connection to server
Serial.println("--> finished transmission\n");
}
else {
// If Arduino can't connect to the server (your computer or web page)
Serial.println("--> connection failed\n");
}
}
Bon mot de passe .... – Farkie
