MQ6 LPG Gas Sensor Module - Compoden
MQ6 Gas Sensor Module — LPG, Butane, Propane Detection
The MQ6 gas sensor module is designed to detect combustible gases such as LPG, iso-butane, and propane. It provides an analog output voltage proportional to the gas concentration, making it suitable for gas leak detection and safety systems. Its high sensitivity and fast response time ensure reliable performance in both hobbyist and industrial applications.

Compatibility
Works with 5V microcontrollers such as Arduino Uno, Mega, Nano. Also compatible with ESP8266 and ESP32 when using the analog input pin. The module outputs 0–5V analog signal, so an ADC is required. Pair with a relay module for automated gas shut-off systems.
Wiring Notes
Connect VCC to 5V, GND to ground, and AO to an analog input (e.g., A0 on Arduino). Allow 20–30 seconds for preheating. Ensure sensor is placed in a well-ventilated area to prevent false triggers. Pull-up resistors are not needed as the module includes built-in conditioning circuitry.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the MQ6 module works with Arduino Uno. Connect AO to analog pin A0, and read the voltage to determine gas concentration.
Does it detect natural gas (methane)?
The MQ6 is optimized for LPG and propane. For methane, consider the MQ4 sensor. The MQ6 may show some response to methane but not as accurate.
How do I calibrate the sensor?
Calibration involves exposing the sensor to a known gas concentration and adjusting the load resistor. For basic applications, the pre-calibrated module provides sufficient sensitivity.
