In every corner of the city, natural gas brings warmth and convenience to our lives, but it also harbors hidden safety hazards that cannot be ignored. How can we make home gas use safer? Tensensor's MQ-G4 semiconductor combustible gas sensor is the "smart heart" tailor-made for home gas alarms, protecting the safety of every family with its superior performance and reliable quality.

    🔍 Precise Sensing, Rapid Response

    MQ-G4 is highly sensitive to flammable gases such as natural gas, methane, liquefied petroleum gas, hydrogen, and town gas. Under standard testing conditions, its response time (T⏱) is ≤20 seconds and recovery time (T⏳) is ≤30 seconds, triggering an alarm at the first sign of a gas leak, giving families valuable time to react.

    🌡️ Strong Adaptability, Consistent Stability

    Whether in the harsh cold of northern winters or the humid heat of southern summers, the MQ-G4 operates stably:

    Wide Temperature Range Adaptability: Operating temperature range -10℃ to +50℃, storage temperature -20℃ to +60℃;

    High Humidity Tolerance: Can operate normally in environments with humidity levels below 95% RH;

    Long Lifespan Design: Up to 8 years of product lifespan, reducing replacement frequency and maintenance costs.

    🛡️ Anti-Interference, Anti-Shock, Anti-Poisoning

    MQ-G4 possesses strong anti-interference capabilities to effectively avoid false alarms, addressing the complex gas interference that may exist in the home environment. Meanwhile, its special shock-resistant structural design makes it more robust during transportation and installation, with strong resistance to silicon poisoning, ensuring long-term stability and reliability.

    ⚙️ Easy Integration, Compatible with Mainstream Circuits

    MQ-G4 adopts a standard metal package with rationally designed electrical parameters:

    Heating voltage (VH) and loop voltage (VC) are both 5V±0.1V, compatible with mainstream control circuits;

    The load resistance (RL) is adjustable, facilitating sensitivity adjustment according to actual needs;

    Under standard testing conditions, the heating wire power is ≤800mW, with low power consumption, energy saving and environmental protection.

    🧪 Rigorous Testing, Reliable Data

    Each MQ-G4 sensor undergoes a rigorous aging and testing process:

    Aging time ≥24 hours, ensuring stable performance before leaving the factory;

    In clean air, the voltage drift across the load resistance is ≤10%, demonstrating high stability;

    Detailed gas concentration response curves, temperature and humidity change curves, and long-term stability test data are provided, facilitating system design and calibration by engineers.

    🛠️ Easy to Use, Process-Friendly

    MQ-G4 supports both manual soldering and wave soldering, with a soldering temperature ≤250℃ and a time ≤3 seconds. It adapts to modern production lines while maintaining process-friendliness. The product also provides clear storage and power-on stability recommendations to help users quickly reach optimal operating conditions.

Choosing the MQ-G4 is choosing respect and commitment to life. Shanxi Tengxing Sensor Technology Co., Ltd. is dedicated to providing every family with the most reliable gas safety sensing solutions. Let's join hands to create a safer home environment：
