1pcs MQ-2 DC5V Arduino liquefied flammable gas methane Smoke Gas Sensor Module Picture, Friend.Thanks you love our items, please note: t he post reply ... moreto us.The shipping very slowly now: 1)the bad weather.The plane cann't on work 2)each Countries Customs is very strict now.It need to check each parcel.So it is very slowly and need much time, so: 1.America need 16-25 days.Australia need 35-48 days or more 2.another countries may be need 39-50 days or more 3.sent to the RU post must tell us your full name(second.Middle, father name) and the RU post Insufficient human capacity.May be need to 55-65 days or more if have any question please let me know! thanks for your understanding. DESCRIPTION Module Applications: Can be used for home and factories gas leakage monitoring means. Suitable for the liquefied petroleum gas, butane, propane, methane, smoke, etc. of detection; Module Features: 1. Using high quality dual- panel design, has a power supply indication and TTL signals output indication; 2. Has a DO switch signal(TTL) output and AO analog signal output; 3. TTL output valid signal is low. When the output low signal light can be directly connected microcontroller or relay module) 4. The analog output voltage follows the higher the concentration the higher the voltage. 5. The gas, natural gas, city gas, smoke better sensitivity. 6. There are four screw holes for easy positioning; 7. Product Dimensions: 32(L) 20(W) 22(H) 8. With a long service life and reliable stability 9. Rapid response and recovery characteristics Electrical properties: Input voltage: DC5V power( current) 150mA DO output: TTL digital 0 and 1( 0.1 and 5V) AO output:0.1-0.3 V( relatively clean) The highest concentration of voltage around 4V Special note: The sensor is powered. Needs to warm up around 20S, measured data becomes stable, the sensor fever is a normal phenomenon, because the internal heating wire, if hot is not normal. Wiring: 1. VCC: positive power supply(5V) 2. GND: tied to power suppl
