20200402· 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 MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.

This sensor module has an MG811 onboard as the sensor component. There is an onboard signal conditioning circuit for amplifying output signal and an onboard heating circuit for heating the sensor. The MG811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, indoor air monitoring application. The output voltage of the ...

20200821· This gas sensor uses a MQ2 gas sensor to indicate if there is gas in the area. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. The alert just shows a red led and starts beeping. This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of ...

It can detect combustible Carbon Monoxide, Coal Gas and Liquefied Gas. The sensitivity can be adjusted by the potentiometer. Hardware Overview This is an Analog output sensor. It needs to be connected to any one Analog socket in Grove Base Shield. It is possible to connect the Grove module to Arduino directly by using

Sensirion Gas Index Algorithm Arduino Library. Sensirion''s Gas Index Algorithm software provides a VOC and an NOx Index output signal calculated from the SGP40/41 raw signal inputs SRAW_VOC and SRAW_: for SGP40, only SRAW_VOC is available. This algorithm enables robust detection of ambient changes of VOCs and NOx with minimal sensortosensor variation.

20140329· CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable …

20210505· Hi first a quick explaination of ''where I am coming from'' : I recently had a quote for the replacement and recalibration of the CO2 and CO sensors in my Anton Sprint 2000xt £350 and the sensors are only good for 2 years so another £350 in 2 years time ! What is the Anton ? It is a portable combustion gas analyzer the type used by gas/oil boiler service engineers.
