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. It’s 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 potentiometerThe 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: 5VAnalog and Digital outputOperating temperature: -20°C to 50°CStorage temperature: -20°C to 70°CSensitivity: 200 to 10000 ppmApplication:Domestic gas leakage detector.Gas leakage alarm system.Industrial Combustible gas detector.Portable gas detector.
