1 CHAPTER V IMPLEMENTATION AND TESTING 5.1 Implementation Arduino IDE This project uses the arduino IDE application. This application used to compile and to upload the program. The program can be seen as below: 1. Libraries. #include <ESP8266WiFi.h> #include "ThingSpeak.h" #include <Time.h> #include <TimeAlarms.h> #include <Servo.h> #include <SPI.h> #include <SD.h> 2. Setting the name and the password of WiFi. const char* ssid = "redmiku"; const char* password = " "; 3. Setting the name of server (thingspeak and IP laptop/pc), setting channel of IoT, and setting API of IoT. unsigned long mychannelnumber = ; const char * mywriteapikey = "R9VHNWY87JFE23QW"; const char* server = "api.thingspeak.com"; const char* server1 = " "; //ip laptop 4. Declaring variable and pinout will be used. const int chipselect = D4; //pin of micro SD module int trigair =D0; // pin trigger of the HC-SR04 int echoair =D1; // pin echo of HC-SR04 int tinggiair; //used to save the water level 12

2 13 int tinggiember=21; // set the height of aquarium int trigpin =D2; // pin trigger of the HC-SR04 int echopin =D3; // pin echo of HC-SR04 float volume; // used to save the volume of fish feed can int tinggipenampung=15; // set the height of fish feed can int tinggipakan; // used to save the height of fish feed int buzzer =D2; // pin of buzzer 5. Setting transfer rate to serial and setting sensor as input/output. Serial.begin(115200); pinmode(trigpin, OUTPUT); pinmode(echopin, INPUT); pinmode(trigair, OUTPUT); pinmode(echoair, INPUT); pinmode(buzzer, OUTPUT); 6. Declaring micro servo variable and pin will be used. Setting the angle of micro servo. myservo1.attach(d8); //servo penampung myservo1.write(0); 7. Connecting to WiFi. Serial.println(); Serial.print("Connecting"); Serial.println(ssid); 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());

3 14 8. Detecting micro sd memory. if (!SD.begin(chipSelect)) { Serial.println("Card does not exists"); // don't do anything more: return; Serial.println("card initialized."); 9. Detecting file jam.txt. The time.txt used to setting the clock. File datafile3 = SD.open("time.txt"); // if the file is available, write to it: if (datafile3) { while (datafile3.available()) { int data1 = datafile3.parseint(); // ambil data ke-1 int data2 = datafile3.parseint(); // ambil data ke-2: int data3 = datafile3.parseint(); // ambil data ke-3: int data4 = datafile3.parseint(); // ambil data ke-3: int data5 = datafile3.parseint(); // ambil data ke-3: int data6 = datafile3.parseint(); // ambil data ke-3: if (datafile3.read() == '\n') { int data1 = data1; int data2 = data2; int data3 = data3; int data4 = data4; int data5 = data5; int data6 = data6; Serial.println(data1); Serial.println(data2);

10 21 telling the server that we are over transmitting the message client.println(); // Empty line client.println(); // Empty line client.stop(); // Closing connection to server else { // If Arduino can't connect to the server (your computer or web page) Serial.println("--> connection failed\n"); 15. Sending data (volume and the water level) to IoT server. ThingSpeak.writeFields(myChannelNumber, mywriteapikey); delay(15000); // ThingSpeak will only accept updates every 15 seconds PHP File In this project PHP file use to get the data (volume, date, month, year, hour, minute, second, the water level) from sensor. After that, save the data to txt file. <html> <body> <?php if(isset($_get["volume"]) && isset($_get["tanggal"]) && isset($_get["bulan"])&& isset($_get["tahun"]) && isset($_get["jam"]) && isset($_get["menit"]) && isset($_get["detik"]) isset($_get["tinggiair"])) { $volume = $_GET["volume"]; $tanggal = $_GET["tanggal"]; $bulan = $_GET["bulan"]; $tahun = $_GET["tahun"]; &&

11 22 $jam = $_GET["jam"]; $menit = $_GET["menit"]; $detik = $_GET["detik"]; $tinggiair = $_GET["tinggiAir"]; $file = fopen("coba.txt","a"); //a untuk menambah data, w untuk menulis baru if($file) { fputs($file,$tanggal."-".$bulan."-".$tahun."\n"); fputs($file,$jam.":".$menit.":".$detik."\n"); fputs($file,"volume Pakan=".$volume."\n"); fputs($file,"tinggi Air=".$tinggiAir."\n\n"); fclose($file); else{ echo "data tidak ada <br>"; echo "<b></b>isi dari file coba.txt sekarang:</b><br>"; $file = fopen("coba.txt","r"); while(! feof($file)) { echo fgets($file).

12 Testing The figure below shows how the nodemcu connected to the WiFi, the nodemcu detected the micro SD memory, the nodemcu detected the time.txt and the alarm.txt, the nodemcu reading the HC-SR04 sensor in measuring the distance, the nodemcu reading the volume, the nodemcu reading the water level, the volume and the water level in txt file, the volume and the water level in IoT server. 1. Connecting to the WiFi. When the nodemcu connected to the WiFi, the nodemcu will get an IP address. The IP address will be print in serial monitor. Figure 8: NodeMCU Connected the WiFi

13 24 2. Detecting the micro SD Memory. When the micro SD memory detected, the serial monitor will be print card initialized. Figure 9: Detecting Micro SD Memory 3. Detecting the time.txt and the alarm.txt. The time.txt used to set the time in nodemcu. The alarm.txt used to set the schedule to open and to close the door of fish feed can. When the time.txt and the alarm.txt detected, the serial monitor will be print the contain of time.txt and the contain of the alarm.txt. Figure 10: Detecting the time.txt and the alarm.txt

14 25 4. Setting the time. After detected the time.txt in micro SD memory, the time will be set. The time will be loop in this program. Figure 11: Setting the time

15 26 5. Measuring the distance using HC-SR04 sensor. The HC-SR04 sensor will read the distance of fish feed can and read the distance of the water level. The distance will be print in serial monitor (jarak). The height of fish feed will be print too in serial monitor. To determine the height of fish feed, this program setting the height of canned fish feed beforehand. After that, the height of canned fish feed minus the distance. To calculating volume of fish feed can, this program using tube volume formula. After that the volume will be print in serial monitor. The distance and the water level will be print in serial monitor. But to know the water level this program set the height of aquarium. After that the height if aquarium minus the distance. Figure 12: Measuring the distance using HC-SR04 sensor
