Mais informação

1. Size: 32mm X22mm X30mm length * width * height 

2. The main chip: LM393, MQ135 gas sensing probe 

3. Operating voltage: DC 5V

Features: 

1. Signal output indicator instructions; 

2. Dual signal output (analog output, and TTL level output); 

3. TTL output valid signal is low; (output low signal light, which can be accessed microcontroller IO port) 

4. Analog output with increasing concentration, the higher the concentration, the higher the voltage; 

5. Sulfide, benzene Department of steam, smoke and other harmful gases with high sensitivity; 

6. Has a long life and reliable stability; 

7. Rapid response recovery characteristics;

Applications: 

A hazardous gas detection apparatus for the family, the environment, suitable for ammonia, aromatic compounds, sulfur, benzene vapor, smoke and other gases harmful gas detection, gas-sensitive element test concentration range: 10 to 1000ppm

 

Code:

int sensorValue;

void setup()
{
  Serial.begin(9600);      // sets the serial port to 9600
}

void loop()
{
  sensorValue = analogRead(0);       // read analog input pin 0
  Serial.println(sensorValue, DEC);  // prints the value read
  delay(100);                        // wait 100ms for next reading
}
