 two-way signal output (TTL level output and analog output)
 TTL output signal for low level effectively (when the low output electric signal lights at ordinary times,
can be directly by single chip microcomputer)
 analog 0 - 5V voltage, the higher the concentration, the higher the voltage
 it has a high sensitivity and good selectivity to ethanol steam
 rapid response recovery features
• used in motor vehicles and other no drunken drivers homework personal on-site testing,
also used in other places of ethanol vapor detection

MQ-4:
 using high-quality dual-panel design, with power indicator and TTL signal output instructions
 with a DO switch signal (TTL) output and AO analog signal output
 TTL output valid signal is low (when the output low signal light can be directly connected microcontroller or relay module)
 the analog output voltage, the higher the concentration the higher the voltage
 methane, natural gas has better detection sensitivity
 there are four screw holes for easy positioning
 size: 32*20*22 mm
 with a long service life and reliable stability
 rapid response and recovery characteristics
• 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
 using high-quality dual-panel design, with power indicator and TTL signal output instructions
 with a DO switch signal (TTL) output and AO analog signal output
 TTL output valid signal is low (when the output low signal light can be directly connected microcontroller or relay module)
 the analog output voltage, the higher the concentration the higher the voltage
 for gas, natural gas has better detection sensitivity
 there are four screw holes for easy positioning
 size: 32*20*22 mm
 with a long service life and reliable stability
 rapid response and recovery characteristics
• input voltage: DC5V power (current): 150mA
