Payment Methods:

The MQ-3 Alcohol Gas Sensor Module is designed to detect alcohol vapors and measure their concentration in the air. This sensor is commonly used in applications such as breath analyzers, alcohol detection systems, and other devices requiring the measurement of ethanol levels.

Key features:

  • High Sensitivity to Alcohol: Specifically tuned to detect ethanol vapors with high sensitivity, making it ideal for applications focused on alcohol detection.
  • Analog Output: Provides an analog voltage output that varies with the concentration of alcohol in the air. This output can be read by analog-to-digital converters (ADC) on microcontrollers for further processing and analysis.
  • Pre-Calibrated: Comes pre-calibrated for convenience, though periodic recalibration may be necessary to maintain accuracy over time.
  • Fast Response Time: Quickly responds to changes in alcohol concentration, providing timely and accurate measurements.
  • Versatile Applications: Suitable for use in breathalyzers, safety systems, and alcohol detection in various environments including vehicles, workplaces, and home applications.
