## Description

The Octopus MQ3 Alcohol Sensor Brick from ElecFreaks is an analogue gas sensor module with high sensitivity to alcohol vapour. It outputs an analogue voltage proportional to the detected alcohol concentration, making it straightforward to interface with Arduino and other microcontrollers. The MQ3 sensor element has low sensitivity to benzene and other gases, providing reasonable selectivity for alcohol detection applications. The brick-style form factor includes a 3-pin connector for easy plug-and-play wiring. Key Features MQ3 Alcohol Sensor – High sensitivity to alcohol vapour Analogue Output – Voltage proportional to detected concentration Fast Response – Quick detection with stable, long-life sensor element Simple Interface – 3-pin analogue connection, 5V powered Brick Form Factor – Octopus series compatible for easy integration Specifications Sensor: MQ3 Detection Target: Alcohol vapour Interface: Analogue Supply Voltage: 5V Dimensions: 42.4 × 31.4mm Ideal For Alcohol vapour detection experiments Air quality and gas sensing projects Arduino sensor prototyping Warning: This sensor is for hobbyist and educational use only. It is not suitable for safety-critical alcohol detection or legal breath-testing applications. Package Contents 1× Octopus MQ3 Alcohol Sensor Brick
