Story

This device is still in process but they do function. So I wanted to publicize them as well as put them on the contest.

Dust alarm device informs you how dusty atmosphere is right now so that you can prepare mask if you have to, or whether you can air the room. Of course there are weather towers measuring the atmosphere but they are not precise in that they aren't here with you. They might malfunction or maybe installed too high to accurately show the current status. Most of all, this device can measure the air quality in your home.

It is very crude since it could not be made till deadline.

Now let's talk about why I came up with this theme.

Chinese yellow dust is a serious health hazard in Korea (and it's worse in China but that's not where I live.)

Chinese yellow dust originates from Chinese deserts and flies over the sea as permanent west wind blows. Because they contain micro heavy metal particles that are emitted from Chinese factory, they are very harmful.

This is exactly why I made this.

This looks a bit better. It is still crude but it works.

Now let me introduce you how I made this.

This is basically a simple sensor connection - connect your GP2Y1010AUO dust censor to your board and read the input. This input shows how dusty the atmosphere is. That's it. Very simple.

However, they need to be connected via bread board since they won't connect right into the board. I didn't want to bother stripping wires so bread board is definitely recommended here.

You can see the schematic for the better understanding.

Code

The Code

//#define BLYNK_USE_DIRECT_CONNECT

#define BLYNK_PRINT Serial

#include <BlynkSimpleCurieBLE.h>
#include <CurieBLE.h>
#include <Servo.h>

// You should get Auth Token in the Blynk App.

char auth[] = "YourAuthToken";

BLEPeripheral  blePeripheral;

int led = 13;

int reading1;


Servo servo1;
Servo servo2;
Servo servo3;
Servo servo4;
WidgetLED led1(V5);

WidgetLED led6(V10);
WidgetLED led7(V11);
WidgetLED led8(V12);

BLYNK_WRITE(V1)
{
  reading1 = param.asInt();
}
BLYNK_WRITE(V2)
{
  reading2 = param.asInt();
}
BLYNK_WRITE(V3)


void setup() {
  Serial.begin(9600);
    pinMode(led, OUTPUT);
  digitalWrite(led, HIGH);

  servo1.attach(3);
  servo2.attach(5);
  servo3.attach(6);
  servo4.attach(9);
  
  delay(1000);

  blePeripheral.setLocalName("k");
  blePeripheral.setDeviceName("k");



}

void loop() {
 
  if (reading1 == LOW) {
    servo1.write(92);
    led1.on();
    led5.off();
  } else {
    servo1.write(70);
    led1.off();
    led5.on();
  }
  if (reading2 == LOW) {
    servo2.write(90);
    led2.on();
    led6.off();
  } else {
    servo2.write(74);
    led2.off();

    led8.on();
  }

   Blynk.run();
  blePeripheral.poll();
}
