DESCRIPTION:

Sensitive material MQ-3 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When present in the environment in which the alcohol vapor sensor , a conductivity sensor with increasing concentration of alcohol gas in air is increased . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. High MQ-3 gas sensor sensitivity to alcohol , gasoline resistant to interference , smoke, water vapor . This sensor can detect various concentrations of alcohol atmosphere , is a low-cost sensors for a variety of applications

Module Applications:

Other places ethanol vapor detection of alcohol ( ethanol ) testing, field testing for motor vehicle drivers and other non- drinking and operating personnel , but also for

Module Features :

1 , using high-quality dual-panel design, with power indicator and TTL signal output instructions;

2 , the switching signal having a DO (TTL) output and analog output AO ;

3, TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )

4 , analog output voltage , the higher the concentration the higher the voltage .

5 , for the detection of alcohol have better sensitivity.

6 , there are four screw holes for easy positioning ;

7 Product dimensions : 37MM (L) * 23MM (W) * 23 (H)

8 , has a long life and reliable stability

9 , rapid response and recovery characteristics

Electrical properties:

Input voltage : DC5V Power consumption ( current ): 150mA

DO output : TTL digital 0 and 1 ( 0.1 and 5V)

AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V

Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .

Wiring:

1, VCC: positive power supply (5V)

2, GND: power supply is negative

3, DO: TTL switching signal output

4, AO: analog signal output

Tags: sensors , gasdetection , ethanol , mq-3 , mq3 , mq 3
