 # MQSensorsLib
-Con esta libreria puedes leer cualquier tipo de gas con los sensores MQ.
+
+This is a unified library to use sensors MQ: 2, 3, 4, 5, 6, 7, 8, 9, and 135.
+
+## Getting Started
+
+```
+MQsensorLib Sensor1(MQ4);
+ppmMethano = Sensor1.readPPM();
+```
+
+### Prerequisites
+
+You'll need Arduino desftop app 1.8.9 or later.
+
+### 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.
