Aside from the MQ-3 sensor, a servo engine and an LED are additionally interfaced with the controller board to move the dial and demonstrate a perilous degree of utilization through an LED sign. The perusing taken by the sensor is shown on a 16X2 character LCD. The Arduino sketch figures...
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...
Breath Analyzer with Arduino To build a reliable alcohol level sensor using the MQ-3, we need to determine the R0 of the device first. We can use this sketch for that: void setup() { Serial.begin(9600); } void loop() { float sensor_volt; float RS; // Get the value of RS via ...
The MQ-3 Alcohol Sensor Module features four pins, two of which are for VCC and GND. The other two may simultaneously output analog and digital data, much like the other basic sensor modules. We're utilizing the Arduino's 5V pin to power the circuit since the module's working voltage ra...
Alcohol tracker,led,arduino,eye twitch sensorThis paper aims to build a framework for keeping the vehicle protected and shielding it by the intruder's occupation. When running by less conscious we cannot take care of our own. When we do all the vehicles with an automated safety system that ...

- This project presents the design and implementation of an Alcohol Detection with Engine Locking for cars using the Ultrasonic Sensor and Arduino UNO as the MCU (Master Control Unit). The system will continuously monitor level of alcohol concentration in alcohol detection sensor and thus turn off...
A proposed sensor detecting alcohol concentrations level in sanitizer is fabricated by employing Polymethyl Methacrylate (PMMA) and Polyvinyl alcohol (PVA) coated glass substrate as a sensing platform. The platform is integrated with Arduino Nano as a data acquisation in order to real...
Arduino Compatible Compiler for LabVIEWAlcohol sensorBreathalyzerThis paper describes a driver alcohol detection system based on breath sample testing, developed using Arduino Compatible Compiler for LabVIEW (ACCL), that allows to program Arduino boards with Labview. The system is able to measure the ...
The ripeness of banana was identified from its color and alcohol level, utilizing MQ-3 gas sensor and TCS34725 color sensor. The built device has consisted of Arduino Mega, ANFIS for classification tool, and NodeMCU as the IoT Gateway. Google Firebase was used as an IoT platform and a data...
