Product Features:

🔹 Gas Detection

• Carbon Monoxide (CO)
• Flammable gases (such as Methane, Liquefied Petroleum Gas (LPG), Propane)

🔹 High Sensitivity

• Strong response to CO and combustible gases, ideal for air quality monitoring and alarm systems.

🔹 Fast Response and Recovery Time

• Quickly detects changes in gas concentration and recovers promptly.

🔹 Adjustable Sensitivity

• Built-in potentiometer allows fine-tuning of the detection threshold as needed.

🔹 Dual Output Design

• Analog Output (AO): Continuous voltage output corresponding to gas concentration.
• Digital Output (DO): High/Low level signal when gas concentration exceeds the set threshold.

🔹 Low Power Consumption

• Suitable for long-term operation or battery-powered applications.

🔹 Simple Wiring Interface

• Fully compatible with Arduino, ESP32, Raspberry Pi, and other development boards.

🔹 Preheat Requirement

• Recommended to preheat the sensor for 24–48 second before first use for optimal detection accuracy.

🔹 Durable Design

• Long service life, ideal for continuous monitoring applications.
