With the widespread use of liquefied petroleum gas (LPG) in home kitchens, restaurants, and industrial gas systems, the safety hazards caused by gas leaks are receiving increasing attention. Achieving early, accurate, and reliable gas leak warnings has become a crucial aspect of safety assurance. Tensensor's MQ-K5B semiconductor gas sensor is an ideal choice optimized for propane (the main component of LPG) detection.

Semiconductor C3H8 Gas Sensor MQ-K5B

    Core Advantages: Designed Specifically for Propane Detection

    MQ-K5B sensor utilizes advanced tin dioxide semiconductor sensing material, exhibiting low conductivity in clean air. However, once a flammable gas is present in the environment, the conductivity increases significantly with increasing concentration. It has high sensitivity to propane while demonstrating good anti-interference capabilities against interfering gases such as alcohol, effectively reducing false alarms and improving alarm reliability.

    Technical Highlights: Stable, Long-Lasting, and Easy to Use

    Wide Concentration Response Range: Detects propane concentrations between 300 and 10000 ppm, covering the entire process from trace leaks to high-concentration hazardous conditions.

    Long-term stability: Designed for a lifespan of up to 10 years, rigorously aged and tested to meet long-term online monitoring needs.

    Low power consumption and simple circuitry: Heating power consumption ≤1W, supports DC or AC heating, simple drive circuitry, easy integration into various alarm devices.

    Excellent environmental adaptability: Stable performance under standard temperature and humidity conditions (20℃±2℃, 55%±5%RH), with temperature and humidity characteristic curves provided for user reference and calibration.

    Wide range of applications: 

    The MQ-K5B sensor is widely used in:

    Household gas leak alarms

    Industrial combustible gas alarms

    Portable gas detectors

    Whether for kitchen gas safety monitoring or industrial gas leak early warning, the MQ-K5B provides rapid response and accurate judgment.

    Quality assurance stems from professionalism: 

    Tensensor focuses on sensor technology research and development and production. MQ-K5B sensor undergoes rigorous testing and quality control to ensure consistent performance and reliability in every unit. The product meets standard testing conditions and provides detailed usage specifications and soldering recommendations for easy integration and use.

    In conclusion, with gas safety receiving increasing attention today, choosing a reliable, fast-responding, and long-life gas sensor is the first step in ensuring the safety of life and property. The MQ-K5B, with its accurate response to propane, excellent anti-interference capabilities, and long service life, has become a reliable choice in the field of liquefied petroleum gas leak detection.
