MQ gas sensor Digital Read - Sensors - Arduino Forum

· 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 ...

MQ4 Methane Gas Sensor : Pinout, Interfacing with Arduino ...

Gas sensors are quite useful devices for controlling pollutants in the air. Similar is the MQ4 Methane Gas sensor. The MQ4 sensor is a compact gas sensor which is highly sensitive to methane gas and less prone to alcohol and other gases. This methane gas sensor provides an output signal according to the sensed concentration of CH4 in the surrounding or environment. This sensor is proved to be ...

Sensor for air/gas flow - Sensors - Arduino Forum

· I'm looking for a sensor to read the flow rate of CO2. This is a relatively low flow situation, where it'll take 6 months to flow the gas from a 5 pound tank. The working pressure is generally in the 30 PSI range. The gas is flowing through 3/16" silicon tubing, so hose barbs are convenient, though I can make anything work. I've found a few that can do it, but they are all a bit more than I'm ...
