NATURAL GAS METHANE GAS SENSOR MODULE MQ4

Description

The Natural Gas Methane Gas Sensor Module is designed to detect methane and other flammable gases in the air with high sensitivity and reliability. Based on the MQ-series gas sensor, it provides both analog and digital outputs, making it easy to interface with microcontrollers like Arduino, Raspberry Pi, or other development boards. This module is commonly used in gas leakage detection systems, safety monitoring devices, and DIY electronics projects.

Features:

It adopts high quality double panel design with power indication and TTL signal output indication; It has DO switch signal (TTL) output and AO analog signal output; The TTL output valid signal is low. (When the output is low, the signal light is on it can be directly connected to the MCU or relay module)

NATURAL GAS METHANE GAS SENSOR MODULE 

The voltage of the analog output, the higher the concentration, the higher the voltage. It has good sensitivity to gas and natural gas detection. Has a long service life and reliable stability Fast response recovery characteristics
