Sensor Suhu dan Kelembaban Arduino Bluetooth Android

1. FINAL PROJECT
BRAVERA MAHA DANTA 120216025
JAMES PHILIP MONTOLALU 13021106048
ADIWARMAN PUTRA PAPUTUNGAN 13021106099
Aplikasi Teknologi Nirkabel

2. Project :
Merangkai Sensor Suhu dan Kelembaban
Arduino Uno
 Input  Sensor Suhu dan Kelembaban DHT 11
 Process  Mikrokontroler Arduino UNO, Bluetooth HC-05
 Output  LCD, Serial Monitor , Android

3. Alat dan Bahan

5. Cara Perakitan
 Sensor Suhu DHT11:
(+) di pin POWER 3.3V
(-) di pin POWER GND
(output) di pin 2
 Bluetooth HC-05
VCC di pin POWER 5V
GND di pin POWER GND
TX di pin 11
RX di pin 10
 LCD i2c
VCC kabelnya di gabung dengan kabel VCC dari HC-05 di pin POWER 5V
GND di pin POWER GND
SCL di pin Analog in A5
SDA di pin Analog in A4

6. Setelah pemasangan lakukan coding
pada arduino
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,16,2);
#include <SoftwareSerial.h>
SoftwareSerial Genotronex(11, 10);
#include "DHT.h"
#define DHTPIN 2
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);

7. void setup() {
lcd.init();
lcd.backlight();
lcd.clear();
Genotronex.begin(9600);
Genotronex.println("connected");
Serial.begin(9600);
Serial.println("DHTxx test!");
dht.begin();
}
void loop() {
delay(2000);
float h = dht.readHumidity();
float t = dht.readTemperature();
float f = dht.readTemperature(true);
if (isnan(h) || isnan(t) || isnan(f)) {
Serial.println("Failed to read from DHT sensor!");
return;
}

8. float hif = dht.computeHeatIndex(f, h);
float hic = dht.computeHeatIndex(t, h, false);
Serial.print("Humidity: ");
Serial.print(h);
Serial.print(" %t");
Serial.print("Temperature: ");
Serial.print(t);
Serial.print(" *C ");
Serial.print(f);
Serial.print(" *Ft");
Serial.print("Heat index: ");
Serial.print(hic);
Serial.print(" *C ");
Serial.print(hif);
Serial.println(" *F");
lcd.print("Humidity :");
lcd.setCursor(1,1);
lcd.print(h);
lcd.setCursor(7,1);
lcd.print("%");
delay(1500);
lcd.clear();
delay(100);
lcd.print("Suhu:");
lcd.setCursor(6,0);
lcd.print(t);
lcd.setCursor(12,0);
lcd.print("*C");

9. lcd.setCursor(6,1);
lcd.print(f);
lcd.setCursor(12,1);
lcd.print("*F");
delay(1250);
lcd.clear();
delay(100);
lcd.print("Heat Indeks:");
lcd.setCursor(0,1);
lcd.print(hic);
lcd.setCursor(5,1);
lcd.print("*C");
lcd.setCursor(8,1);
lcd.print(hif);
lcd.setCursor(13,1);
lcd.print("*F");
delay(1250);
lcd.clear();
delay(250);
Genotronex.print("Humidity: ");
Genotronex.print(h);
Genotronex.println(" %n");
Genotronex.println("Temperature: ");
Genotronex.print(t);
Genotronex.println(" *C ");
Genotronex.print(f);
Genotronex.println(" *Fn");
Genotronex.print("Heat index: n");
Genotronex.print(hic);
Genotronex.println(" *C n");
Genotronex.print(hif);
Genotronex.println(" *F");
delay(1500);
}

10. Kemudian buat Aplikasi Android
dengan APP INVERTOR (home)

11. (about)

12. Tampilan pada serial monitor

13. Tampilan pada handphone

14. Arduino yang sudah jadi
