Air Analyzer, Using Almost All Kinds of MQ Sensors ...

· So I ordered a set of 9 MQ sensors and made this project, in which I can measure the concentration of many kinds of gas in the air only using some MQ sensors. This kind of sensor is not so accurate and needs lots of calibration, but they are the best cheap gas sensors out there. You can find a set of nine gas sensors for only $6 to $7. in my project, I use 6 of them and measure the gas ...

Gas Sensor - Arduino Project Hub

· This gas sensor uses a MQ-2 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 ...

· I've been testing some of this sensors, and all of them have the same "problem".Les talk about MQ2, reading the datasheet it say the heating consumption is less than 800 mW. Measuring the sensor, the consumption is around 114 mA, and the preheat time is over 24 hours!. So you can't use any kind of batteries, a 2000mA battery would last only 12 hours (without counting arduino consumption) …
