 ===== Project implementation =====
+Arduino IDE functions used to record and send the data from the sensor to Webhooks from IFTTTT.
 <code>
-void setup ()
+void setup () {
 //initialize the serial monitor for debugging
-	Serial.begin(115200);
+ Serial.begin(115200);
+ Serial.println("DHT11 sensor!");
+//call begin to start sensor
+ dht.begin();
+// Connect to Wi-Fi
+ WiFi.begin(ssid, password);
+ while (WiFi.status() != WL_CONNECTED) {
+   delay(500);
+   Serial.print(".");
+  }
+  Serial.println("");
+  Serial.println("WiFi connected");
+}
+</code>
+Two rules were set in the project.
+.If the temperature is higher than 25 C, an email is sent through an applet (named high temp) with the message “Temperature too high!”;
+<code>
+if (t > high_temp ){
+    if (!client.connect(host, httpPort)) {
+      Serial.println("connection failed");
+      return;
+    }
+    else
+    Serial.println("conected");
+    client.print(String("POST ") + url_high_low_temp + " HTTP/1.1\r\n" +
+    "Host: " + host + "\r\n" +
+    "Content-Type: application/x-www-form-urlencoded\r\n" +
+    "Content-Length: 41\r\n\r\n" +
+    "value1=" + t +
+    "&value2="+"Temperature too high "+"\r\n");
+    delay(15000);
+}
+  </code>
+.If the temperature is lower than 24 C, an email is sent through the same applet with the message “Temperature too low!”.
+<code>
+if (t < low_temp ){
+  if (!client.connect(host, httpPort)) {
+      Serial.println("connection failed");
+      return;
+  }
+  else
+  Serial.println("conected");
+  client.print(String("POST ") + url_high_low_temp + " HTTP/1.1\r\n" +
+  "Host: " + host + "\r\n" +
+  "Content-Type: application/x-www-form-urlencoded\r\n" +
+  "Content-Length: 40\r\n\r\n" +
+  "value1=" + t +
+  "&value2=" + "Temperature too low "+"\r\n");
+  delay(15000);
+ }
