Description:

Introducing the MQ-2 Smoke LPG Butane Gas Sensor Module, a versatile detector designed to detect gas leaks in both residential and industrial settings. This sensor module is equipped to sense a wide range of gases including H2, LPG, CH4, CO, Alcohol, Smoke, or Propane with high sensitivity and rapid response time, ensuring quick and accurate gas level measurements. With adjustable sensitivity via the onboard potentiometer, this module offers customizable detection capabilities to suit various applications.

Utilizing Tin oxide (SnO2) as its gas-sensitive material, the MQ-2 Gas Sensor exhibits low conductivity in clean air. When exposed to flammable gases, its conductivity increases proportionally to the concentration of the gas in the surrounding air. This change in conductivity is converted into an output signal, providing real-time data on gas concentration levels.


Features:

  • Wide Range Sensitivity: Detects combustible gases with high sensitivity across a wide range of concentrations, ensuring reliable gas detection.
  • Versatile Detection: Highly sensitive to gases such as LPG, Propane, Hydrogen, and more, making it suitable for diverse gas detection applications.
  • Longevity and Affordability: Offers long life and low cost, providing a cost-effective solution for gas detection needs.
  • Simple Drive Circuit: Features a straightforward drive circuit for easy integration into existing systems or projects.
  • Digital or Analog Operation: Can function as both a digital or analog sensor, offering flexibility in usage and compatibility with different systems.
  • Adjustable Sensitivity: The sensitivity of the digital pin can be adjusted using the onboard potentiometer, allowing for fine-tuning of detection parameters.
  • Multi-Gas Detection: Capable of detecting various gases including LPG, Alcohol, Propane, Hydrogen, CO, and methane, offering comprehensive gas monitoring capabilities.

Application Considerations:

  • Avoid Water Condensation: Ensure minimal water condensation on the sensor surfaces to maintain optimal performance.
  • Limit Exposure to High Gas Concentrations: Prolonged exposure to high gas concentrations may affect sensor characteristics.
  • Store Properly: Store sensors in airproof containers with clean air to prevent reversible drift and ensure stability.
  • Protect from Adverse Environments: Shield sensors from high humidity, temperature, pollution, and other adverse conditions to prevent performance degradation.
  • Handle with Care: Avoid continual vibration or strong concussion to prevent damage to the sensor.

Applications:

  • Domestic gas leakage detection
  • Industrial combustible gas detection
  • Portable gas detection

Specifications:

Digital Output Voltage 0V or 5V (TTL Logic)
Preheat Duration(sec) 20
Dimensions (LxWxH) mm 36x20x21

Experience reliable gas detection with the MQ-2 Smoke LPG Butane Gas Sensor Module, your trusted solution for gas leak detection in various environments.
