The MQ3 alcohol sensor detects alcohol concentration in the air, making it useful for breathalyzer applications. It uses a tin dioxide (SnO2) semiconductor material that changes resistance in response to alcohol vapors. The sensor provides both analog and digital outputs, allowing easy integration with microcontrollers. It is widely used in alcohol breath detectors, automotive safety systems, and industrial safety applications. The MQ3 sensor is highly sensitive to ethanol and responds quickly to alcohol vapors. It operates at 5V and requires a warm-up time for accurate measurements. The module is used in alcohol testing devices for detecting intoxication levels.
