High sensitivity to alcohol and small sensitivity to Benzine. They are suitable for alcohol checker, Breathalyser. This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer.
Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. A resistive load between the output pins and ground sets the sensitivity of the detector.
Please note that the picture in the datasheet for the top configuration is wrong.
Both configurations have the same pinout .
The Grove - Gas Sensor ( MQ) module is useful for gas leakage detecting (in home and industry). It can detect Alcohol, Benzine, CH Hexane, LPG, CO. Based on its fast response time.
Measurements can be taken as soon as possible . Also the sensitivity can be adjusted by the potentiometer. MQSensor Datasheet LM3Datasheet. MQ-C2H5OH Gas Sensor Datasheet.
This module is made using Alcohol Gas Sensor MQ3. The output voltage from the Gas sensor increases when the concentration of gas increases. Sensitivity can be adjusted by varying the potentiometer. Development resources: demo codes, schematic, datasheets , etc.
Part Number, Sensitive Gas, Application. MQ-1Gas Sensor , benzene, alcohol, smoke, Air quality monitor. MQ-Gas Sensor , LPG, propane, hydrogen, Gas leakage . It has higher sensitivity to alcohol and lower sensitivity to benzine.
Heater voltage 5V, ohm (40mA consumption) . It is one of the straightforward gas sensors so it works almost the same way with other gas sensors. Typically, it is used as part of the breathalyzers or breath testers for the detection of ethanol in the human breath. It shows features, applications, . The analog gas sensor - MQis suitable for detecting alcohol, this sensor can be used in a. The sensitivity can be adjusted by the potentiometer.
Pin Definition: 1-Output 2-GND - . Small sensitivity to alcohol, smoke. LNG, avoid the noise of alcohol and .
