Interfacing MQ3 Alcohol Gas Sensor to Arduino Embedds

I have been testing the Alcohol Gas Sensor MQ3 for a day or so now and here is what I have learned: 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. I used 5VDC and the sensor draws 133mA. 2: Use a 10K 1% resistor. This will give the best range of readings for the sensor ...
