## Description

This breakout board provides a convenient PCB adapter for MQ-series gas sensors (MQ-3, MQ-4, MQ-6, MQ-7, and MQ-8). It converts the sensor's oversized, oddly-spaced pins into a standard breakout format that's easy to wire up to a microcontroller. Connect 5 V, ground, and a load resistor to an ADC input — that's all that's needed to start reading gas concentration levels. Note: This is the breakout PCB only. The MQ-series gas sensor is sold separately. Key Features MQ-Series Compatible – Fits MQ-3, MQ-4, MQ-6, MQ-7, and MQ-8 sensors Simple Wiring – VCC (5 V), GND, and one ADC connection with load resistor Compact – 16.8 mm diameter round PCB Specifications Compatible Sensors: MQ-3, MQ-4, MQ-6, MQ-7, MQ-8 Operating Voltage: 5 V Diameter: 16.8 mm Ideal For Gas detection and air quality monitoring Hazardous gas alarm prototypes Environmental sensing projects Package Contents 1× Gas sensor breakout PCB (sensor not included) Resources Hazardous Gas Monitor Tutorial Schematic (PDF)
