mq6 gas sensor with arduino and buzzer

MQ gas sensor Digital Read - Sensors - Arduino Forum

06/05/2021· Hi, after some google and blog search, I would like to write my (I think first) entry in this blog. I’m testing a MQ6 sensor connected to Arduino directly. I connected both analog and digital sensor output. analog output is connected to A0 input in Arduino and digital output to pin 7 in Arduino. the code is (is an adapted code from MQ7 example): // Test sensor de gas tipo Butano con Arduino …
