Product Description

Gas sensor MQ4 registers the presence and concentration of natural gas and methane (CH4). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly.
