Alcohol breath tester || IOT

alcohol breath analyzer is to get alert from drunken people.
The micro-controller does the above job it receives the signals from the sensor, and this signals operated under the control of software which is stored in ROM.
In this project we have used hardware equipment like MQ3 gas sensor, Arduino board and Arduino Ethernet board, LAN wire, USB cable, Male to Female wire and in software we use Arduino software. After connection, when a person blows in front of sensor, if he is drunken the value will be more than 300 and it will be increasing rapidly according to consumption of the alcohol. If the person is not drunken the values will be within 200.
