• MQ-4 – Methane Gas Sensor Module

    ₪23.00

    The MQ-4 methane gas sensor is a metal oxide semiconductor (MOS) that detects the presence of methane gases and then provides the result in the form of analog values. In this way, it provides information about the gas concentration, and its range is 300 ppm–10,000 ppm which is enough to detect leakage.
