To work with the Sensor, we must first power it. We use the Arduino UNO Board's 5V and GND pins, and the Sensor's output pin is connected to the Arduino's A0 pin. We have connected an LED to PIN 6 of the Arduino, the analog pin to the A0 pin of the Arduino, and the ground...
The Arduino sketch figures out how to take the perusing from the MQ-3 sensor, digitize and show perusing, contrast perusing and a limit level, and work LED just as servo to demonstrate a risky degree of utilization. The Arduino code is composed of Arduino IDE and consumed to the Pro ...
we can display whether the system has detected alcohol or not. Once the alcohol is detected, it is displayed on an LCD. The buzzer indicates the presence of alcohol. This breath analyzer project is very much helpful. It is a highly sensitive alcohol sensor at the workplace with an alarm...
Grove - Alcohol Sensor is a complete alcohol sensor module for Arduino or Seeeduino. It is built with MQ303A semiconductor alcohol sensor. It has good sensitivity and fast response to alcohol. It is suitable for making Breathalyzer. This Grove implements all the necessary circuitry for MQ303A ...
Connect the Alcohol sensor into the A0 port of Grove Base Shield. In the Arduino IDE, go to the Tools pull-down menu at the top, select Board, and make sure “LinkIt One” is checked. Then pull down the Tools menu again, and select appropriate Serial Port. Connect the Buzzer to the...
