SainSmart MQ131 Ozone Gas Detection Sensor Module

hey everybody it's over here depending on where you live you might have been impacted from the smoke from the western wildfires like we have been here in boulder colorado and i don't know about you but seeing how much the smoke has dirty the air has made me really interested in air composition in general the cool thing is is that we've just released five new mq gas sensors so if you're interested in learning about the air quality around you it's super easy let's check them out the mq series of gas sensors uses a small heater inside with an electrochemical sensor to determine whether a specific gas is present in the air we already carry the mq3 which is the alcohol gas sensor the mq7 the carbon monoxide sensor the mq4 which is the methane cng gas sensor the mq6 the lpg gas sensor and the mq8 the hydrogen gas sensor now we've added an ammonia gas sensor a hydrogen sulfide gas sensor a low
