Alcohol Level Meter using Arduino & MQ-135 Sensor

May 12, 2020· Instead of MQ-135, you can use MQ2, MQ3, MQ5 module as well. Basically, they all have similar functions. This type of sensor circuit can be used as a breathalyzer to check a person’s blood-alcohol level. Just as we exhale carbon dioxide when we breathe out, we also will breathe out some alcohol if we have alcohol in our blood.

How To Use MQ-135 Gas Sensor - Codrey Electronics

Jan 16, 2020· yassin: RLOAD 10000 is for 1oK Load Resistor! As clearly pointed in this post, while using the “MQ-135” library-supported Arduino setup, the gas sensor calibration can be done at by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL-1)x RL, that means Rs = (5V/(sensorValue * (/))-1)*RL.
