This is a unified library to use sensors MQ: 2, 3, 4, 5, 6, 7, 8, 9, 131, 135, 303A and 309A.

MQUnifiedsensor MQ4(pin, 4); //Example if sensor is MQ4, type = 4
float ppmCH4 = MQ4.readSensor();

You'll need Arduino desktop app 1.8.9 or later.

Use calibration systems if you have several sensors that read the same gas.

These tests can re-adjust values defined previously and you can contribute to improve conditions or features obtained from particular scenes.

Examples/MQ-3

These tests may generate statistics validation using descriptive tools for quantitative variables.

Examples/MQ-board.ino

• Data sheets - Curves and behavior for each sensor, using logarithmic graphs.
• Main purpose - Every sensor has high sensibility for a specific gas or material.
