Description

MQ-5 Gas Sensor Module

Description

The MQ-5 is a semiconductor gas sensor designed to detect various combustible gases such as LPG, natural gas, methane, and butane. It provides both analog and digital output signals, making it versatile for many applications.

Key Specifications

  • Operating Voltage: 5V DC

  • Heating Consumption: ≤ 800 mW

  • Load Resistance (RL): Adjustable

  • Heater Resistance (RH): 31 ±10 Ω

  • Sensing Resistance (Rs): 10–60 kΩ

  • Detection Range: 200–10,000 ppm for methane and propane

  • Response Time: Fast response and recovery

  • Sensitivity: High sensitivity to LPG, natural gas, and town gas; low sensitivity to alcohol and smoke

Features

  • Dual output: analog (0–5V) and digital TTL

  • Onboard potentiometer to adjust sensitivity

  • Indicator LEDs for power and digital output

  • Compact design suitable for integration

Important Notes

  • Requires a preheating time of over 24 hours for optimal accuracy

  • Calibration is recommended for precise gas concentration measurements

Applications

  • Gas leakage detection in homes and industry

  • Portable gas detectors

  • Educational and DIY gas sensing projects
