HYDROGEN GAS SENSOR MODULE H2 ALARM DETECT MQ8

Description

The Hydrogen Gas Sensor Module is a reliable gas detection module designed to sense hydrogen (H₂) concentrations in the environment. Equipped with a highly sensitive semiconductor sensor, it provides accurate detection with fast response and recovery times. This module is ideal for use in hydrogen leak detection systems, safety alarms, portable gas detectors, and industrial monitoring applications. With both analog and digital outputs, it integrates seamlessly with Arduino, Raspberry Pi, and other microcontroller platforms for real-time monitoring and alarm triggering.

Features:

Using high-quality dual-panel design, with power indicator and TTL signal output instructions. The switching signal having a DO (TTL) output and analog output AO. TTL output valid signal is low. ( Low-level signal when the output light can directly connect to the microcontroller or relay module )

HYDROGEN GAS SENSOR MODULE H2 ALARM DETECT

The higher the voltage, the concentration of the analog output voltage is higher. A hydrogen gas detection with good sensitivity. There are four screw holes for easy positioning. Has a long life and reliable stability Rapid response and recovery characteristics
