Feature: MQ-2: Detection concentration: 300-1000ppm(combustible gas). MQ-3: Used in motor vehicles and other no drunken drivers homework personnel on-site testing, also used in other places of ethanol vapor detection. Feature: Size: 32 x 22 x 27mm Main chip: LM393, ZYMQ - 3 gas sensors Working voltage: DC 5V 1, With a signal output instructions. 2, Two-way signal output (TTL level output and analog output) 3, TTL output signal for low level effectively.(when the low output electric signal lights at ordinary times, can be directly by single chip microcomputer) 4, Analog 0 - 5V voltage, the higher the concentration, the higher the voltage. 5, To ethanol steam has a high sensitivity and good selectivity. 6, In June and has long service life and reliable stability. 7, Rapid response recovery features. MQ-4: 1, Using high-quality dual-panel design, with power indicator and TTL signal output instructions; 2, With 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, the higher the concentration the higher the voltage. 5, Methane, natural gas has better detection 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 MQ-5: Suitable for home or industrial on LPG, 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, With 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, the higher the concentration the higher the voltage. 5, For gas, natural gas has better detection sensitivity. 6, There are four screw holes for easy positioning; 7, Product Dimensions: 32* 20 * 22 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 MQ-6: Suitable for domestic or industrial on LPG (liquefied petroleum gas) butane, propane, LNG (liquefied natural gas) detection devices. Excellent resistance to ethanol vapor, smoke interference. Module Features: 1, Using high-quality dual-panel design, with power indicator and TTL signal output instructions; 2, With 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, 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage. 5, The propane, butane, LPG, LNG has a good detection 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 MQ-7: For home, carbon monoxide detection device environment.
