Detailed Product Description

  1. Introduction

    This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.

    The latest gas sensor is designed to meet the demand of enviromental protection, it  MQ - 3 gas sensor,with high sensitivity to ethanol, can resist the interference of gasoline, smog, vapor, detect ethanol in the air sensitively.the material of MQ - 3 gas sensor is SnO2 ,which has low conductivity in clean air. With a 3p line connecting  sensor shield(Arduino-Compatible) , through  mega168 controller programming(Arduino-Compatible), it an be made ethanol alarm, alcohol tester with buzzer module and relay module.

    Application:

    For motor vehicle drivers and other non-drinking and operating personnel on-site testing, but also for other places ethanol vapor detection, detection of alcohol range: detection range of 10 ~ 1000ppm

     

    Specifications:

    detection range: 10-100ppm ethanol

    characteristic gas: 125ppm ethanol

    heating voltage: 5 + - 0.2 V (AC·DC)

    loop voltage:24V DC

    load resistance: adjustable

    voltage in clean air: 1.5 V

    service life: 5 years

    Uses the MQ-3 C2H5OH Gas Sensor

    Easy SIP interface

    Compatible with most microcontrollers

    Power requirements: 5 VDC @ 250 mA (Heater On) / 60 mA (Heater Off)

    nterface: 1 TTL compatible input (HSW), 1 TTL compatible output (ALR)

    Dimensions: 1.5 x 1.0 x 1.0 in(38.1 x 25.4 x 25.4 mm)

    Operating temp range: 14°F to 122°F (10°C to 50°C)

    size: 20.5 mm x 41mm

    weight: 6g

    Note: this sensor is equipped with sensitivity adjustment potentiometer: clockwise regulation, reverse adjust small.Such as alcohol by adjusting the sensitivity of the sensor, can obtain satisfactory alcohol concentration fan initiate.
