Factories, Offices, Hospitals, Military and other such industries need to monitor their staff/personnel follow all work ethics that include, not coming to premises under the influence of alcohol or under bad health conditions. This ensures proper work ethics are followed. So our proposed system allows for alcohol & health monitoring plus reporting system that monitors this and reports it to concerned personnel remotely over internet. Our system consists of an IOT based circuit system that uses a microcontroller based circuit system. The system has alcohol as well as blood pressure monitoring sensors to check for alcohol consumption as well as inappropriate blood pressure monitoring. This ensures no occurrences of accidents due to alcohol influence or bad health conditions.

The carelessness and unconsciousness of the drunken drivers creates a huge problems to the people on road. In the modern era, Road Safety is considered to be one of the mostly concerned social issues. The habit of drunken driving causes damage to the surroundings and every person around him. The consumption of alcohol results in unconsciousness and fatigue while driving. The Government has taken many preventive measures to avoid drunken drive accidents. In order to minimise the DUI (Driving Under Influence of alcohol) related accidents, Supreme Court has ordered to shut down all the selling points on National and State Highways . But it’s effective implementation is not possible due to many social political issues. However we can minimise the accidents by installing the proposed system inside the vehicle. This system continuously monitors the air exhaled by the driver with the help of MQ-3 sensor (alcohol sensor) and update these values in cloud through IoT. If any alcohol detection is found above the threshold value then the system stops the vehicle ignition system. This action is achieved by stopping the fuel supply to the ignition system. And also, the deaths due to cardiac arrest while driving is more. So, this system is constructed to monitor the heart beat rate of the driver.
MQ-3 sensor detects the presence of alcohol consumed by the driver. It can sense the alcohol content ranging from 0.04 mg/L to 4 mg/L. It can operates at temperatures between -10’C to 50’C. It requires a minimum power supply of less than 150Ma to 5V.It consists of total 6 pins, but we use only 4 pins. The two pins A, H are used for heating purposes and the other two pins are used for ground and power. The air exhaled by the driver is monitored continuously with MQ-3 sensor and updated in the cloud. When the values detected from the sensor attains the threshold limit, then the vehicle ignition system will stop resulting in accident prevention.
It is available at cheaper price.
It has long life cycle.
It offers high stability.
It has high sensitivity which results into faster response time.
It needs simple drive circuit and it is simple to use.
It is easy to interface with microcontrollers.
Alcohol sensor based car protects you when you are drunk. During such condition, your other family member can drive. Moreover it will protect your car from unauthorized access.
Breath analyzers using alcohol detection are available at high prices. Moreover they have shorter lifetime.
Breath analyzers require continuous re-calibration.
