MQ-6 Module - LPG, Iso-butane and Propane Sensor

The MQ-6 Liquefied Petroleum Isobutane Propane Gas Sensor module is a great way to add gas sensing to your project at a reasonable price. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm. Its sensitivity can be varied by attaching a potentiometer.

The sensor’s output is analog on the output pin and can be used to drive a very simple circuit directly or attached to a microcontroller ADC input.

Features:

• Good sensitivity to a wide range of combustible gases such as: Propane, Butane, and LPG. The unit is also sensitive to Hydrogen and Ethanol steam.
• Adjustable sensitivity via on-board potentiometer
• The module is ready to use (load resistance is already on the module)
• Digital TTL output can be attached to a switching circuit.

Specifications

• Operating voltage: 5V
• Analog and Digital output
• Operating temperature: -20°C to 50°C
• Storage temperature: -20°C to 70°C
• Sensitivity: 200 to 10000 ppm

Typical application:

• Domestic gas leakage detector.
• Gas leakage alarm system.
• Industrial Combustible gas detector.
• Portable gas detector.
