Specification:

Features:

• Multi-Gas Detection:
  Detects Liquefied Petroleum Gas (LPG), natural gas (CH₄), hydrogen (H₂), and methane.

• High Sensitivity:
  Excellent sensitivity to LPG and natural gas with a detection range of 200 to 10,000 ppm.

• Fast Response & Recovery Time:
  Quickly detects gas presence and rapidly returns to baseline after gas is cleared.

• Analog & Digital Outputs:

  • Analog Output (AO): Variable voltage that changes with gas concentration.

  • Digital Output (DO): Goes HIGH when gas concentration exceeds a set threshold (adjustable via onboard potentiometer).

• Adjustable Sensitivity:
  Onboard potentiometer allows you to set the digital threshold to match your detection needs.

• Built-in Indicator LEDs:
  Power and digital signal indicators provide visual feedback for module status.

• Operating Voltage:
  Typically operates at 5V DC.

  Works with Arduino, ESP32, Raspberry Pi, and other development platforms.

• Applications:

  • Gas leak detection systems

  • Household safety devices

Description:

The Simple MQ-5 Gas Sensor Module is an inexpensive way to add basic gas sensing to your project. A Buzzer is used by the MQ-5 Methane LPG Liquid Propane Gas Sensor Module particulate sensor to detect any detected material that is even present in the air!

This MQ-5 Methane LPG Liquid Propane Gas Sensor Module is widely used in gas leak detection pieces of equipment in the home and industry, and is suitable for detecting LPG, natural gas, town gas, as well as avoiding the noise of alcohol and cooking fumes and cigarette smoke.

The MQ5 (MQ-5) sensor is used in gas leakage detection equipment in consumer and industrial applications. It can detect LPG, natural gas, and coal gas. Avoid alcohol noise, cooking fumes, and cigarette smoke. The potentiometer can be used to adjust the sensitivity.

The MQ-5 gas sensor's sensitive material is tin Oxide (SnO2), which has a lower conductivity in clean air. When the target combustible gas is present, the sensor's conductivity increases as the gas concentration rises. Please use a simple electro circuit to convert the change in conductivity to the corresponding gas concentration output signal.

The MQ-5 gas sensor has a high sensitivity to methane, propane, and butane and can detect both methane and propane. The sensor could be used to detect various combustible gases, particularly methane; it is low-cost and suitable for a variety of applications.
