With the development of traffic safety, intelligent vehicles, and portable detection devices, the market demands increasingly higher accuracy and reliability in alcohol detection. MQ-E2-C2H5OH electrochemical alcohol sensor utilizes a fuel cell detection principle, rapidly converting alcohol concentration into a linear electrical signal for accurate and stable alcohol concentration measurement.

    This sensor features high precision, high sensitivity, low power consumption, and strong anti-interference capabilities. Its detection range covers 0–1.0 mg/L, with a maximum measurement limit of 2.0 mg/L and a response time of ≤20 seconds, enabling rapid alcohol concentration detection. Furthermore, its repeatability is ±0.006 mg/L, with a monthly drift of less than 2%, ensuring stable and reliable data over long-term use.

    Compared to traditional semiconductor alcohol sensors, MQ-E2-C2H5OH requires no heating, consumes less power, and offers better output linearity, making it more suitable for applications requiring quantitative analysis. In addition, its product lifespan can reach 3 years, effectively reducing equipment maintenance costs.

    With its superior performance, MQ-E2-C2H5OH is widely used in traffic police breathalyzers, vehicle-mounted alcohol interlocks, portable breathalyzers, enterprise safety management equipment, and smart consumer electronics. Whether for traffic enforcement, driver safety management, or personal health monitoring, it provides a fast and accurate alcohol detection solution.

    If you are looking for a core alcohol detection device that combines high precision, stability, and low power consumption, MQ-E2-C2H5OH electrochemical alcohol sensor is a reliable choice.
