- Its a semiconductor sensor
- It detects the presence of alcohol gases at concentrations from 0.05 mg/L to 10 mg/L.
- The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air.
This MQ-3 Alcohol Detector Gas Sensor Module is simple to use. MQ-3 Alcohol Detector Module which can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides an interface through standard 4 x 0.1″ header pins.
It provides an analogue output corresponding to the concentration of the gas in the air and an easy to use digital output.
The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas. Perfect sensing alcohol concentration on your breath just likes a common breathalyzer.
The digital output can be easily interfaced to microcontrollers and other circuits. The analogue output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings.
-10°C ~ +70°C
0.05 mg/L ~ 10 mg/L Alcohol

1 x MQ3 Mq-3 Alcohol Ethanol Gas Sensor Module Breathalyzer Works With official Arduino Boards (Red and Black)
A very good Alcohol Ethanol Gas Sensor Module Breathalyzer with a very unique and innovative design structure. Suits the official Arduino Boards . Definitely recommended to anyone looking for a funky and cool looking Alcohol Ethanol Gas Sensor Module Breathalyzer . Looks better than the conventional Module Breathalyzer and very impressive. The build quality is also fine and looks long-lasting.
Works good and made up of good quality materials and Iam satisfied with the product.
Detects alcohol in Listerine and other alcohol containing products using Arduino UNO. Yet to quantify the actual alcohol vapor content in the air. nice product .... satisfied my requirement in the project.Thank you Robotbanao.
The alcohol sensor is working smoothly. Packaging and shipping is very good. Price is little bit high. Otherwise nice item. 10/9. I recommend it to buy. Thanks.
