In today's era of rapid technological development, gas detection technology is an important means to ensure production safety, environmental protection and the quality of daily life. Its importance is self-evident. Propane gas, as a common combustible gas, is widely used in industrial production and daily life. However, the leakage of propane gas may bring serious safety hazards. Once propane gas leaks and accumulates to a certain concentration, it may cause fire or even explosion when encountering open flames or high temperatures, posing a huge threat to people's lives and property safety.

    With the acceleration of the industrialization process and the improvement of people's requirements for the quality of life, the requirements for gas detection technology are also getting higher and higher. Traditional gas detection methods often have problems such as low detection efficiency, poor accuracy, and complex operation, which are difficult to meet the needs of modern society. The MQ-K5B propane gas sensor adopts advanced multi-layer thick film manufacturing technology and exquisite electrode preparation technology to ensure the stability and reliability of the sensor. It has broad application prospects in the field of gas detection, providing users with reliable early warning information, thereby effectively avoiding potential safety hazards.

    The gas-sensitive material used in the MQ-K5B gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is combustible gas in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the concentration of combustible gas in the air. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration. 

    The MQ-K5B gas sensor is highly sensitive to propane and has strong anti-interference ability to alcohol and some other interfering gases.
