Semiconductor C3H8 Gas Sensor MQ-K5B

    Core Technology and Product Advantages

    MQ-K5B adopts a mature semiconductor gas-sensitive principle. It exhibits low conductivity in clean air, but its conductivity increases with concentration when exposed to combustible gases such as propane. Combined with a simple circuit, it can output a stable concentration signal, offering reliable performance and strong adaptability.

    Propane-Specific Sensitivity and Outstanding Anti-Interference Capability

    1. It has a high selective response to propane, with a detection range covering 300~10000ppm, meeting the dual needs of leak early warning and concentration monitoring.

    2. Strong suppression of common interfering gases such as alcohol and cooking fumes, significantly reducing false alarms and suitable for complex environments such as kitchens, workshops, and warehouses.

    3. Under standard conditions, sensitivity S≥5 (Rs air / Rs 5000ppm propane), providing clear signals, rapid response, and quick leak detection.

    User-friendly operating conditions and lower operating costs

    1. Both heating voltage and circuit voltage are 5.0V±0.1V, resulting in a simplified drive circuit that facilitates integration into alarms, detectors, and other terminal products.

    2. Heating power consumption ≤1W, a low-power design that extends device lifespan and overall lifespan.

    3. Standard plastic encapsulation, compact size, easy soldering, and easy mass assembly. Manual soldering is compatible with lead-free and halogen-free processes; stable operation is achieved at temperatures ≤350℃ and durations ≤3 seconds.

    Ultra-long lifespan and maximum stability

    1. Designed for a lifespan of up to 10 years, far exceeding conventional sensors, significantly reducing replacement and maintenance costs.

    2. Preheating Specifications: New devices ≥ 48 hours; for long-term storage, extend the aging time accordingly. After power-on, it exhibits rapid stabilization and excellent consistency.

    3. Strong temperature and humidity adaptability; optimal performance is achieved in standard environments of 20℃±2℃ and 55%±5%RH, maintaining reliable output across a wide environmental range.

    Comprehensive Safety Protection for Worry-Free Use

    Avoids risks such as silicon compounds, highly corrosive gases, halogens, water accumulation, and overpressure. With proper use and storage, performance remains stable over time.

    Rapid response and recovery; stable sensitivity during long-term operation, meeting 24-hour uninterrupted monitoring requirements.

    Comprehensive Application Coverage

    MQ-K5B caters to both civilian and industrial safety monitoring, adapting to propane detection needs in multiple fields. It is the core "sensing heart" of gas safety equipment.
