{"title":"Octopus MQ3 Alcohol Sensor Brick","handle":"octopus-mq3-alcohol-sensor-brick","url":"/products/octopus-mq3-alcohol-sensor-brick","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.\n\nThe 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.\n\nKey Features\n\n\nMQ3 Alcohol Sensor – High sensitivity to alcohol vapour\n\nAnalogue Output – Voltage proportional to detected concentration\n\nFast Response – Quick detection with stable, long-life sensor element\n\nSimple Interface – 3-pin analogue connection, 5V powered\n\nBrick Form Factor – Octopus series compatible for easy integration\n\n\nSpecifications\n\n\nSensor: MQ3\n\nDetection Target: Alcohol vapour\n\nInterface: Analogue\n\nSupply Voltage: 5V\n\nDimensions: 42.4 × 31.4mm\n\n\nIdeal For\n\nAlcohol vapour detection experiments\nAir quality and gas sensing projects\nArduino sensor prototyping\n\n\n\nWarning: This sensor is for hobbyist and educational use only. It is not suitable for safety-critical alcohol detection or legal breath-testing applications.\n\n\nPackage Contents\n\n1× Octopus MQ3 Alcohol Sensor Brick\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4603,"title":"Default Title","sku":"EF-EF04060","price":12.14,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
