Description

Features:

The MQ-8 is a semiconductor sensor designed for detecting hydrogen gas (H2). It uses a SnO2 sensing layer that increases conductivity in the presence of hydrogen, delivering a signal readable via a simple circuit. With strong selectivity for hydrogen and resistance to interference from other gases, it offers a reliable, cost-effective solution for hydrogen detection in residential and industrial environments.
