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.
