Gas Sensor
Gas sensors, also known as gas detectors or gas leak detectors, 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:
DFROBOT, WINSEN, ASAIR, ACEBOTT, SHARP MICROELECTRONICS, AOSONG, SHARP, RENESAS, PLANTOWER, SENSIRION, INFINEON, MEMSFRONTIER, MASTECH, SEEED STUDIO, FIGARO, MIKROE, PIMORONI, ADAFRUIT, and WAVESHARE.
Whether you’re working on prototyping, air purification systems, or smart industrial controls, our gas sensors offer precision, durability, and peace of mind.
