Edspert.id Final Project: Intensive Bootcamp Internet of Things Batch-10

Green House is a building for plant cultivation that has a translucent roof and wall structure. Farmers are helped by the existence of this Green House, but it still requires certain conditioning in order to achieve what is desired. This is usually done traditionally, so it is considered less effective, especially in an era full of sophisticated technology like today. In addition, theft and building break-ins are topics that need attention in addition to vegetable maintenance. This project was created to help farmers to manage their Green House quickly and precisely both in close and long distances. This project has been carried out and took approximately 1 month. The system can monitor air temperature, air humidity, soil moisture, light intensity, pump status, door status, and security alarms. In addition, this system has also been provided with automatic pump control and automatic door lock features, so that this can increase efficiency in maintaining vegetables and security in the Green House area. This system is based on the Internet of Things (IoT), using HTTP as the communication protocol. The system interface uses the MIT App Inventor application.

Wiring

Scanning the I2C Address on the LCD

#include <Wire.h>

void setup() {
  Wire.begin();
  Serial.begin(115200);
  while (!Serial); // Wait for serial monitor
  Serial.println("\nI2C Scanner");
}

void loop() {
  int nDevices = 0;
  Serial.println("Scanning...");

  for (byte address = 1; address < 127; ++address) {
    // The i2c_scanner uses the return value of the Wire.endTransmission to see if a device did acknowledge to the address.
    Wire.beginTransmission(address);
    byte error = Wire.endTransmission();

    if (error == 0) {
      Serial.print("I2C device found at address 0x");
      if (address < 16) {
        Serial.print("0");
      }
      Serial.print(address, HEX);
      Serial.println("  !");

      ++nDevices;
    } else if (error == 4) {
      Serial.print("Unknown error at address 0x");
      if (address < 16) {
        Serial.print("0");
      }
      Serial.println(address, HEX);
    }
  }
  if (nDevices == 0) {
    Serial.println("No I2C devices found\n");
  } else {
    Serial.println("done\n");
  }
  delay(5000); // Wait 5 seconds for next scan
}

Arduino IDE Setup

1. Open the Arduino IDE first, then open the project by clicking File -> Open :

   • Final_Project_Edspert_Batch10_ESP32Project.ino • Final_Project_Edspert_Batch10_NodeMCUProject.ino

   
   

2. Fill in the Additional Board Manager URLs in Arduino IDE

   Click File -> Preferences -> enter the Boards Manager Url by copying the following link : https://dl.espressif.com/dl/package_esp32_index.json http://arduino.esp8266.com/stable/package_esp8266com_index.json

   
   

3. Board Setup in Arduino IDE

   i	How to setup the DOIT ESP32 DEVKIT V1 board
   • Click Tools section -> Board -> Boards Manager -> Install esp32. • Then click Tools -> Board -> ESP32 Arduino -> DOIT ESP32 DEVKIT V1.

   
   

   ii	How to setup the NodeMCU V3 ESP8266 Lolin board
   • Click Tools section -> Board -> Boards Manager -> Install esp8266. • Then click Tools -> Board -> ESP8266 Boards -> NodeMCU 1.0 (ESP-12E Module).

   
   

4. Change the Board Speed in Arduino IDE

   i	How to change the speed of DOIT ESP32 DEVKIT V1 board

   ii	How to change the speed of NodeMCU V3 ESP8266 Lolin board
   Click Tools -> Upload Speed -> 115200

   
   

5. Install Library in Arduino IDE

   Download all the library zip files. Then paste it in the: C:\Users\Computer_Username\Documents\Arduino\libraries

   
   

6. Port Setup in Arduino IDE

   Click Port -> Choose according to your device port (you can see in device manager)

   
   

7. Change the WiFi Name, WiFi Password, and so on according to what you are currently using.
   
   

8. Before uploading the program please click: Verify.
   
   

9. If there is no error in the program code, then please click: Upload.
   
   

10. Some things you need to do when using the ESP32 board :

    • Arduino IDE information: Uploading... -> immediately press and hold the BOOT button. • Arduino IDE information: Writing at .... (%) -> release the BOOT button. • Wait until the message appears: Done Uploading -> The program is directly operated. • Press the EN (RST) button and then Restart to handle the ESP32 board that cannot process the SC. • Do not press the BOOT and EN buttons at the same time as this may switch to Upload Firmware mode.

    
    

11. As for program upload, the NodeMCU board is superior because it can generally be done automatically.
