#92629 I have a code that displays the temperature from sensors on the website.
I need this data to go to the mysql database every 1 hour.
Can someone help
Code: Select all#include <ESP8266WebServer.h>
#include <OneWire.h>
#include <DallasTemperature.h>

// Data wire is plugged into port D2 on the ESP8266
#define ONE_WIRE_BUS D2

// Setup a oneWire instance to communicate with any OneWire devices
OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);

float tempSensor1, tempSensor2, tempSensor3;

uint8_t sensor1[8] = { 0x28, 0xFF, 0x10, 0x52, 0x00, 0x16, 0x02, 0x10 };
uint8_t sensor2[8] = { 0x28, 0xFF, 0x1C, 0xA5, 0x00, 0x16, 0x02, 0xC8 };
uint8_t sensor3[8] = { 0x28, 0x61, 0x64, 0x12, 0x3F, 0xFD, 0x80, 0xC6 };

/*Put your SSID & Password*/
const char* ssid = "Dom"; // Enter SSID here
const char* password = "789789"; //Enter Password here

ESP8266WebServer server(80);

void setup() {


Serial.println("Connecting to ");

//connect to your local wi-fi network
WiFi.begin(ssid, password);

//check wi-fi is connected to wi-fi network
while (WiFi.status() != WL_CONNECTED) {
Serial.println("WiFi connected..!");
Serial.print("Got IP: "); Serial.println(WiFi.localIP());

server.on("/", handle_OnConnect);

Serial.println("HTTP server started");
void loop() {

void handle_OnConnect() {
tempSensor1 = sensors.getTempC(sensor1); // Gets the values of the temperature
tempSensor2 = sensors.getTempC(sensor2); // Gets the values of the temperature
tempSensor3 = sensors.getTempC(sensor3); // Gets the values of the temperature
server.send(200, "text/html", SendHTML(tempSensor1,tempSensor2,tempSensor3));

void handle_NotFound(){
server.send(404, "text/plain", "Not found");

String SendHTML(float tempSensor1,float tempSensor2,float tempSensor3){
