MQSensorsLib
This is a unified library to use sensors MQ: 2, 3, 4, 5, 6, 7, 8, 9, 131, 135, 303A and 309A.
Getting Started
#define placa "Arduino UNO"
#define Voltage_Resolution 5
#define pin A0 //Analog input 0 of your arduino
#define type "MQ-4" //MQ4
#define ADC_Bit_Resolution 10 // For arduino UNO/MEGA/NANO
MQUnifiedsensor MQ4(placa, Voltage_Resolution, ADC_Bit_Resolution, pin, type); //Example if sensor is MQ4 on Arduino UNO board
MQ4.setRegressionMethod("Exponential"); //_PPM = a*ratio^b
MQ4.setA(1012.7); MQ4.setB(-2.786); // Configurate the ecuation values to get CH4 concentration
MQ4.setR0(3.86018237);
MQ4.init();
MQ4.update();
float ppmCH4 = MQ4.readSensor();

Installing
Clone this repository 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 tests can re-adjust values defined previously and you can contribute to improve conditions or features obtained from particular scenes.
Examples/MQ-3
And coding style tests
These tests may generate statistics validation using descriptive tools for quantitative variables.
Examples/MQ-board.ino
Built With
- Data sheets - Curves and behavior for each sensor, using logarithmic graphs.
- Main purpose - Every sensor has high sensibility for a specific gas or material.
