Gas sensors, also known as gas detectors or gas leak detector, are critical electronic components used to detect toxic, combustible, or hazardous gases and measure gas concentrations in various environments. These sensors are essential for safety, air quality monitoring, and industrial automation.

Our collection includes a broad range of high-performance gas sensors, including the popular MQ series:

• MQ-2 – Methane, Butane, LPG, Smoke
• MQ-3 – Alcohol, Ethanol, Smoke
• MQ-4 – Methane, CNG Gas
• MQ-5 – Natural Gas, LPG
• MQ-6 – LPG, Butane
• MQ-7 – Carbon Monoxide
• MQ-8 – Hydrogen Gas
• MQ-9 – Carbon Monoxide, Flammable Gases
• MQ131 – Ozone
• MQ135 – Air Quality (CO, Ammonia, Benzene, Alcohol, Smoke)
• MQ136 – Hydrogen Sulfide
• MQ137 – Ammonia
• MQ138 – Benzene, Alcohol, Propane, Formaldehyde, Hydrogen
• MQ214 – Methane, Natural Gas

We feature gas sensors from top global brands including:
