## Description

The MQ-3 is an alcohol gas sensor suitable for detecting alcohol concentration in the air, similar to a breathalyser. It provides an analog resistive output based on alcohol concentration, with high sensitivity and fast response time. The drive circuit is simple — just one resistor is needed, and the output can be read by a 0–3.3V ADC. Key Features Alcohol Detection – High sensitivity to alcohol vapour concentration Analog Output – Resistive output proportional to gas concentration Simple Interface – Requires only one external resistor Operating Voltage – 5V DC or AC circuit Heater Consumption – Less than 750mW Operating Temperature – -10°C to 70°C Specifications Diameter – 16.8mm Height – 9.3mm (without pins) Ideal For Breathalyser projects Air quality monitoring Arduino and microcontroller gas detection projects Package Contents 1× MQ-3 alcohol gas sensor Note: This sensor requires a heater voltage to operate. Refer to the datasheet for ppm conversion details and warm-up requirements. Resources MQ-3 Datasheet (PDF)
