Factory direct MQ-2 smoke gas sensor module methane liquefied flammable gas for Ardu

Factory direct MQ-2 smoke gas sensor module methane liquefied flammable gas for Ardu
Product Detailed
Factory direct MQ-2 smoke gas sensor module methane liquefied flammable gas for Ardu Product Description

MQ-2 gas sensor using gas-sensitive materials with lower conductivity in clean air tin oxide (SnO2). When the sensor their environment, the presence of flammable gas, the sensor's conductivity increases with the increase of the concentration of combustible gases in air. Changes in the conductivity can be converted to the corresponding output signal of the gas concentration using a simple circuit.

MQ-2 gas sensor for liquefied petroleum gas, propane, high sensitivity of hydrogen, natural gas and other flammable vapor detection. This sensor can detect a variety of flammable gas, is a low-cost sensor suitable for a variety of applications.Module applications:Gas leak monitoring means, suitable for liquefied petroleum gas, butane, propane, methane, smoke, etc., the probe can be used in homes and factories;Module Features:1, using high-quality dual-panel design, with a power indicator and TTL signal output instructions;2, with a the DO switch signal (TTL) output, and AO analog signal output;3, TTL output valid signal is low. (When the low output signal light can be connected directly to the microcontroller or relay module)4, 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.5 of liquefied natural gas, city gas, smoke better sensitivity.6, there are four screw holes for easy positioning;Product Dimensions: 36 (L) * 19 (W) * 22 (H)8, with a long life and reliable stability9, rapid response and recovery characteristicsModule using the instructions:Explanation: Use Preheat 20SInput voltage: the DC5V power consumption (current): 150mADO output: TTL digital 0 and 1 (0.1 and 5V)AO output :0.1-0 .3 V (relative pollution), and maximum concentration voltage of about 4VSpecial note: the sensor is powered Preheat 20S stable measurement data, sensor fever is a normal phenomenon, because the internal heating wire, if hot is not normal.
