## Getting Started
```
2019-08-15 09:18:13 -05:00
MQUnifiedsensor MQ4(pin, 4); //Example if sensor is MQ4, type = 4
float ppmCH4 = MQ4.readSensor();

### Installing
Clone this repositry into your desktop machine
```
git clone https://github.com/miguel5612/MQSensorsLib
```
## Running the tests
Use calibration systems if you have several sensors that read the same gas.
### Break down into end to end tests
These test can re-adjust values defined previously and you can contribute to improve conditions or features obtained from particular scenes.
```
testMassive.ino
```
### And coding style tests
These tests may generate statistics validation using descriptive tools for cuantitative variables.
```
testStatics.ino
```
## Built With
* [Data sheets ](https://github.com/miguel5612/MQSensorsLib/tree/master/Datasheets ) - Curves and behavior for each sensor, using logarithmic graphs.
* [Main purpose ](https://github.com/miguel5612/MQSensorsLib/blob/master/static/img/bg.jpg ) - Every sensor has high sensibility for a specific gas or material.
