Sensitive fabric MQ-7 fuel sensors used in clean air, low conductivity tin oxide (SnO2).
High-low temperature biking detection mode (1.5V heating) carbon monoxide detector, conductivity sensor with the increasing concentration of carbon monoxide fuel in the air will increase,high-temperature (5.0V heating) cleansing cryoadsorption stray gases.
Using a simple circuit to alternate the conductivity, attention of the fuel is converted to the corresponding output signal.
MQ-7 gasoline sensor of excessive sensitivity for carbon monoxide, this sensor can come across a spread of gases containing carbon monoxide, is a low-value sensors for a diffusion of packages.
| SPECIFICATIONS | |
| Input voltage | DC5V Power consumption ( current ) |
| DO output | TTL digital 0 and 1 ( 0.1 and 5V) |
| AO output | 0.1-0 .3 V ( relative to pollution ),the maximum Concentration of a voltage of about 4V |
| Special note | After the sensor is powered, needs to warm up around 20S,measured data was stable, heat sensor is a normal phenomenon, because the internal heating wire,if hot is not normal . |
| Wiring | |
| VCC | positive power supply (5V) |
| GND | power supply is negative |
| DO | TTL switching signal output |
| AO | analog signal output |
OVERVIEW:
-Using high-quality dual-panel design,with power indicator and TTL signal output instructions.
-The switching signal having a DO (TTL) output and analog output AO.
-TTL output valid signal is low. ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
-Analog output voltage with the higher concentration of higher voltage
-There are four screw holes for easy positioning.
-Has a long life and reliable stability
-Rapid response and recovery characteristic
PACKAGE INCLUDES:
1 PCS x Mq 7 Co Carbon Monoxide Coal Gas Module

/*
AnalogReadSerial
Reads an analog input on pin 0, prints the result to the Serial Monitor.
Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
This example code is in the public domain.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}
