## Overview

The MQ-6 LPG Gas Sensor Module is a compact, high-sensitivity detector designed for flammable gases like propane, butane, and methane. Operating at 5V DC with low power consumption, it offers both TTL digital and analog outputs for easy integration with popular microcontrollers such as Arduino and Raspberry Pi. Featuring a dual-panel design with power indicators and quick warm-up time, this sensor ensures fast, reliable gas leak detection for home or industrial safety applications.

## Description

Detection Singing high-quality dual panel design, with power indicator and instructions for TTL signal output; The switching signal has a DO (TTL) output and an analogue output AO; The valid TTL output signal is low. (Low level signal when the output light can be connected directly to the microcontroller or relay module) Analog output voltage with the higher concentration of higher voltage. A gas, natural gas, city gas, smoke better sensitivity. There are four screw holes for easy positioning; Has a long service life and reliable stability Fast response and recovery properties Input voltage: DC5V power consumption (current): 150mA DO output: TTL digital 0 and 1 (0.1 and 5V). AO output: 0.1-0.3V (relative to pollution), the maximum concentration of a voltage of about 4V Special note: After the sensor is powered, it needs to warm up by 20 s, the measured data was stable, the heat sensor is a normal phenomenon, because the internal heating wire when it is hot is not normal. VCC: positive power supply (5V). GND: power supply is negative DO: TTL switching signal output. AO: analogue signal output.

## Features

- Includes 9 detectors for flammable toxic gases, very complete gas detector set
- Can be used for home and factory gas leak monitoring device, which can be used for LPG, butane, propane, methane, smoke and other detection;
- The use of high-quality double panel design, with power indicator and TTL signal output instructions;
- The valid TTL output signal is low. (When the output is low signal, can be connected directly to the microcontroller or relay module)
- The higher the voltage, the higher the voltage the analogue output voltage.
