MQ2 Gas Sensor + Arduino: How to Detect Dangerous Fumes ...

20190605· Main chip: LM393, ZYMQ2 gas sensor; Working voltage: DC 5V; MQ2 Features. With signal output command. Dual signal output (analog output and high/low digital output). 0~ analog output voltage, the higher the concentration, the higher the voltage. It has higher sensitivity to natural gas, natural gas and city gas. Long service life, stable ...


Gas Sensor Arduino Project Hub

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 ...
