In this tutorial we will see how we can interface the MQ-3 Gas Sensor with Aries v2.0 Board.<\/p>\n\n\n\n

The MQ3 alcohol sensor can detect alcohol concentrations ranging from 25 to 500 ppm. The sensor\u2019s analog output voltage (at the A0 pin) varies in proportion to the alcohol concentration. The higher the concentration of alcohol in the air, the higher the output voltage; the lower the concentration, the lower the output voltage. <\/p>\n\n\n\n

Finding the threshold values<\/h3>\n\n\n\n

To estimate the level of alcohol intoxication, you need to record the values your sensor outputs when you blow on it before and after consuming alcohol.<\/p>\n\n\n\n

Note:<\/p>\n\n\n\n

If you are not legally permitted to consume alcoholic beverages, use an isopropyl alcohol bottle or any hand sanitizer bottle for your testing. Don\u2019t get alcohol on the sensor. Simply squeeze the bottle to allow the alcohol vapours to enter the sensor and take your readings.<\/p>\n\n\n\n
