Introduction: Air Quality Monitoring Device Using Arduino
Hi every one
living one of the developing country or most polluted city knowing Air quality is very important for health , i make this device for my self and every one can make it as well . here I am going to demonstrate how to make.
before i do here intervals and the terms describing the AQI air quality levels are as follows:
From 0 to 50....................good
From 51 to 100..................moderate
From 101 to 150.................unhealthy for sensitive groups
From 151 to 200.................unhealthy
From 201 to 300.................very unhealthy
From 300........................hazardous
unit :ppm (parts per million )
Step 1: Electronic Components
you need this project
1- Arduino ( any arduino types )
2-gas sensor
3-jumper wires (3pc )
4-Breadboard
5-Arduino usb cable
6- Arduino IDE
Connecting Arduino to sensor
MQ- 2- Gas sensor have 4 pin , u need to use 3 of them as shown in figure
pin A0 to pin A0 in arduino
pin vcc to pin 5v
pin GRN to GRN
Step 2: CODE
Download code here ........
int airquality = 0;
void setup()
{ Serial.begin(9600);
}
void loop()
{
int sensorValue = analogRead(A0);
Serial.print("Air Quality = ");
Serial.print(sensorValue);
Serial.print("*PPM");
Serial.println();
delay(1000);
}
Step 3: Result
After compiling, uploading and running it, in the Serial Monitor (Tools -> Serial Monitor or Ctrl + Shift + M) the sensor will send data!
serial monitor will shown u I hope you enjoyed this project and if there is something wrong or not clear please let me know. follow me for many more projects to come
Thanks for reading.
