************************************************************************************************************************************************
MQ sensor reading library for arduino
Note: remember that all the parameters below can be modified during the program execution with the methods:
setR0, setRL, setA, setB where you will have to send as parameter the new value, example: MQ4.setR0(20); //R0 = 20K
Authors: Miguel A. Califa U - Yersson R. Carrillo A - Ghiordy F. Contreras C
Contributors: Andres A. Martinez - Juan A. Rodríguez - Mario A. Rodríguez O
Sensor: MQ-4
Supply voltage: 5V
R0: - Sin determinar -
RL: 10KOhm
Model: Logarithmic regression with parameters.
a = 10000 | b = 50000
Development board: Arduino
