MQ-3 Alcohol Ethanol Sensor Breath Gas Detector Ethanol Detection For Arduino

Feature:
 
2. It has DO switch signal(TTL) output and AO analog signal output.
3. TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can directly connect single chip microcomputer or relay module) 
4. Analog output voltage with concentration, the higher concentration, the higher voltage.
5. Has better sensitivity to the liquefied petroleum gas, natural gas, city gas, smoke.
6. Has long service life and reliable stability 
7. Rapid response recovery features
 
Specification:
 
Input voltage: DC5V 
Power consumption (current) : 150 mA 
DO output: TTL digital 1 and 0 (0.1 and 5 V) 
AO output: 0.1-0.3 V (pollution-free)
Highest concentration of voltage: Approx 4 V 
Detection range of alcohol: detection range of 10 ~ 1000 PPM
 
Connection mode: 
 
1. VCC: Positive (5 v) 
2. GND: Connect power negative 
3. DO: TTL switch signal output
4. AO: Analog signal output
