MQ-5 Methane Natural Gas Sensor Shield Liquefied Electronic Detector ModuleMQ-5 sensor Introduction :Sensitive material MQ-5 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor , conductivity sensor with increasing concentration of combustible gases in air increases . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-5 gas sensor of high butane , propane, methane sensitivity, methane and propane can be better taken into account. This sensor can detect a variety of combustible gases, especially natural gas , is a low-cost sensor for a variety of applications . Suitable for home or industrial liquefied petroleum gas , natural gas, coal gas monitoring devices. Excellent resistance to alcohol, smoke interference.Module Features :1 , using high-quality dual-panel design, with power indicator and TTL signal output instructions;2 , the switching signal having a DO (TTL) output and analog output AO ;3, TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )4 , the higher the voltage , the concentration of the analog output voltage is higher.5 , for gas, natural gas has a better detection sensitivity .6 , there are four screw holes for easy positioning ;7 , Product dimensions : 32 (L) * 20 (W) * 22 (H)8 , has a long life and reliable stability9 , rapid response and recovery characteristics Electrical properties:Input voltage : DC5V Power consumption ( current ): 150mADO output : TTL digital 0 and 1 ( 0.1 and 5V)AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4VSpecial note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .Before purchase:1.All the goods are ready stock, we will arrange the shipment at once if we receive the order.2.Please read the item description, if you have any question, do not hesitate to contact us.3.Use the vouchers for more saving.Shipment：1.1-2 days to ship(except for the pro-order item) After purchase:1.If you are satisfied，please give us 5 stars praise. 2.Please contact us before you are going to give us bad review.
