Product Introduction
SMT-06 is a semiconductor type gas sensor used to detect combustible gases. The conductivity of the sensor's sensing material will change accordingly with the concentration of the target gas. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration. The SMT-06 gas sensor is highly sensitive to butane, propane, and methane. This sensor can detect a variety of combustible gases, especially liquefied gas (propane). It is a low-cost sensor suitable for a variety of applications.
