It is Arduino compatible. Rs: sensor resistance at various concentrations of gases. The MQ- 3 is suitable for. The drive circuit is very simple, datasheet all it needs is one resistor. 4 is mq3 shows the typical dependence of the MQ- 5 on temperature and humidity. The MQ- 3 Gas sensor datasheet makes it easy to monitor alcohol using our I2C Mini Module mq3 form factor.

05 mg/ L to 10 mg/ L. Standard work condition. Some modules have a built- in variable resistor module to adjust mq3 the sensitivity of the sensor. MQ3 Alcohol Gas Sensor Module is used for detecting alcohol concentration on your breath, like a Breathalyzer. ppm R s / R o H2 LPG CH4 CO alcohol Air. This sensor has a high sensitivity and fast response mq3 time. Features a wide detecting scope high sensitivity with a stable, , fast response time simple drive circuit.

It is not a substitute datasheet for a police officer' s datasheet breathalyzer. These little devices may be used in gas leakage detectors. This item: Waveshare MQ- 3 Alcohol Ethanol Gas Sensor Module Gas Detector Sensor Alcohol Detection Sensor for. It can detect H2 CH4, Alcohol, LPG, Smoke, CO Propane. Due to mq3 its high sensitivity fast response time measurements can be taken as soon as possible. Grove - Gas Sensor( MQ3) The Grove - mq3 Gas Sensor( MQ3) module is useful for gas mq3 leakage detection ( in home and industry). The MQ- 2 Gas Sensor module is useful for gas leakage detecting in home and industry.

I am not responsible for it being off. The MQ3 is connected to an ADC121C 12- Bit Analog to Digital converter, which module is capable expanding to 9 gas sensors per I2C port using just two address jumpers ( making full use of the floating address system). SPECIFICATIONS A. It is a low cost semiconductor sensor which can detect the datasheet presence of alcohol gases at concentrations from 0. Mq3 alcohol sensor module datasheet. The module outputs a voltage from 0 to 5V relative to the alcohol concentration. It can detect LPG alcohol, propane, datasheet hydrogen , i- butane, methane smoke. Disclaimer: The alcohol sensor used was not calibrated ( see the datasheet for that) mq3 and is not very accurate. It has a high sensitivity and fast response time.

Ro: sensor resistance at datasheet 1000ppm of H2 in air at datasheet 33% RH and 20 mq3 degree. * Fast response long life * Simple drive circuit APPLICATION They are suitable for alcohol checker, High sensitivity * Stable Breathalyser.

Alcohol datasheet

MQ- 3 Semiconductor Sensor for Alcohol Gas Profile Sensitive material of MQ- 3 gas sensor is SnO 2, which with lower conductivity in clean air. When the target alcohol gas exist, the sensor’ s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond. The MQ- 3 is a heater- driven alcohol sensor that outputs an analog signal ( usually interpreted somewhere between 1 depending on how long you let the sensor warm up), which through the use of your Arduino code and calibration, can be interpreted for whatever use you need. I have been testing the Alcohol Gas Sensor MQ- 3 for a day or so now and here is what I have learened: 1: It takes 48 hours to fully " condition" the sensor. Meaning that you have to keep power applied for that long before the readings will settle and become reliable.
