High-Performance MQ-Series Gas Sensor Modules for Arduino Projects

Enhance your Arduino projects with our premium selection of MQ-series gas sensor modules, designed for Arduino enthusiasts and electronic hobbyists. Our range includes the popular MQ-2, MQ-3, MQ-4, MQ-5, MQ-6, MQ-7, MQ-8, MQ-9, and MQ-135 gas sensors, each engineered for precise gas detection and accurate measurement in a variety of applications.

Key Features of MQ Gas Sensor Modules:

• Dual-panel design for enhanced reliability, with clear power indicator and TTL signal output instructions.
• Versatile integration with both digital (TTL) and analog output signals, ensuring compatibility with microcontrollers, Arduino boards, and relay modules.
• TTL output signal activates in a low state, providing direct connectivity options for projects.
• Analog output voltage fluctuates with gas concentration, offering accurate measurement for precise gas level monitoring.
• Easy mounting with four screw holes, making the sensor module simple to position.
• Exceptional durability and stability, built to last for extended use.
• Rapid response and recovery time, ideal for real-time gas monitoring.
• Features high-quality SnO2 (tin oxide) sensors for accurate detection of gases in clean air environments.
• Operating voltage: DC 5V; Power consumption: 150mA.
• Digital Output (DO): TTL 0 and 1 (0.1V and 5V).
• Analog Output (AO): 0.1-0.3V (correlates to pollution levels), with a max concentration of around 4V.

Important Note: Upon powering on, the sensor requires a 20-second warm-up period for accurate readings. The sensor may emit some heat during this process due to its internal heating wire. If the sensor becomes excessively hot, please inspect it for potential issues.
