MQ-5 Gas Sensor Module – LPG, Methane (Sui Gas) & Natural Gas Detector for Arduino in Pakistan

Overview

The MQ-5 Gas Sensor Module is a high-sensitivity sensor designed specifically for the detection of flammable gases. It is particularly effective at detecting LPG (Butane/Propane) and Natural Gas (Methane), while showing lower sensitivity to cigarette smoke and alcohol. This makes it much more reliable for kitchen safety applications where you don’t want false alarms from cooking or cleaning.

Key Features 

• Specialized Sensitivity: High response to Natural Gas (Methane) and LPG; perfect for Pakistani households using Sui Gas.

• Dual Output Mode:

  • Digital (D0): Provides a simple 0 or 1 signal. Connect this to a buzzer for an instant “Gas Detected” alarm.

  • Analog (A0): Provides a continuous voltage value ($0\text{V}$ to $5\text{V}$) to measure the exact concentration of gas in the air.

• Adjustable Threshold: The onboard blue potentiometer allows you to set the sensitivity level—preventing false alarms in well-ventilated areas.

• Reliable Stability: Features a long-life SnO2 sensing element that offers stable performance even in humid kitchen environments.
