Power Rating: Operates at 5V DC – ensures stable and energy-efficient performance during continuous operation.

Type: MQ-3 Gas Sensor Module – specifically designed to detect alcohol vapors, ethanol, and smoke in the air.

Detection Range: Sensitive to gas concentrations from 25 to 500 ppm (parts per million), suitable for breath and environmental detection.

Output: Provides both analog and digital outputs for direct interfacing with Arduino, Raspberry Pi, and other microcontrollers.

Response Time: Fast response and recovery allow accurate, real-time detection of alcohol levels.

Calibration: Adjustable sensitivity using the onboard potentiometer for precise measurement control.

Build Quality: Features a durable metal-oxide semiconductor sensing element with an anti-corrosive mesh for long service life.

Applications: Commonly used in breath analyzers, vehicle safety systems, alcohol detection projects, and air quality monitoring devices.
