Introduction
This analog gas sensor - MQ3 is suitable for detecting alcohol. It can be used in a Breath analyzer. Also it has high sensitivity to alcohol and low sensitivity to Benzine.
The sensitivity can be adjusted by a blue potentiometer on the sensor.
Note: this module should be used together with EASY plug control board.
Specification
- Connector: Easy plug
- Power supply: 5V
- Sensor type: Digital and Analog
- Simple drive circuit
- Stable and long service life
- Quick response and High sensitivity
Technical Details
- Dimensions: 56mm*20mm*18mm
- Weight: 7.5g
Connect It Up
Connect the EASY Plug analog alcohol sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.
Upload the Code
Copy and paste below code to Arduino IDE and upload.
int gas_din=2;
int gas_ain=A7;
int led=13;
int ad_value;
void setup()
{
pinMode(led,OUTPUT);
pinMode(gas_din,INPUT);
pinMode(gas_ain,INPUT);
Serial.begin(9600);
}
void loop()
{
ad_value=analogRead(gas_ain);
if(digitalRead(gas_din)==LOW)
{
digitalWrite(led,HIGH);
Serial.println("Alcohol leakage ");
Serial.println(ad_value);
}
else
{
digitalWrite(led,LOW);
Serial.println("Alcohol not leak");
Serial.println(ad_value);
}
delay(500);
}
What You Should See
Done uploading the code, open the serial monitor and set the baud rate to 9600. If the sensor detects the alcohol in the air, you should see the value change.
