Gas Sensor - Arduino Project Hub

2020-08-21· 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 ...

LPG Sensor with MQ-6 and Arduino | Microcontroller Tutorials

MQ-6 Gas Leak Detector. If you want to detect only the presence of LPG in the air, you only need to connect the AO pin to any analog pin of the Arduino UNO. Then you must determine the threshold value by placing the MQ-6 near a safe LPG source (like an unignited gas stove) and record the reading. Note that the MQ-6 needs at least 20 seconds to ...
