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 ...
