Carbon Monoxide Gas Sensor MQ-7 - Arduino Project Hub

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.

MQ-135 Gas Sensor with Arduino Code and Circuit Diagram

· But, in this project, we will only play a buzzer. We will also include one red and one green LED. Circuit Diagram for MQ-135 gas sensor. We are going to receive analog value from the sensor. We used the Arduino A5 pin. So we connected the A5 pin with the 4th pin in the sensor. The sensor GND and VCC goes to Arduino GND and 5volt.

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 ...

· Ok. Just to close this so others reading this thread can use the code. I enden up not reporting the CRC check as I cant get it to work. The readings from the sensor are fine and have been verified with another flowmeter. In the code is an offset so flows in one way are reported as positive numbers and the other way is negative. There is also a ...

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 ...

Using A Flow Sensor With Arduino - BC Robotics

The sensor works with anywhere between 5-18VDC but since we are working with 5VDC logic on the Arduino, we will just use the Arduino’s own 5V power by way of the USB port at this time. Start by connecting one of the jumper wires from the 5V pin on the Arduino and running it over to the positive rail on the side of the solderless breadboard.
