Features:<\/span>
\n1. High quality double panel design, with power indicator and TTL output signal.
\n2. Have DO switch signal(TTL) output and AO analog signal output.
\n3. TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can be directly connect single chip microcomputer or relay module)
\n4. Analog output voltage with concentration, the higher concentration, the higher voltage.
\n5. Has better sensitivity with the liquefied petroleum gas, natural gas, city gas, smoke.
\n6. Has long service life and reliable stability
\n7. Rapid response recovery features\n

Specifications:
\nInput voltage: DC5V
\nPower consumption (current) : 150 mA
\nDO output: TTL digital 1 and 0 (0.1 and 5 V)
\nAO output: 0.1-0.3 V (pollution-free)
\nHighest concentration of voltage: Approx 4 V
\nDetection range of alcohol: detection range of 10 ~ 1000 PPM<\/p>\n

Connection mode:
