Factory Worker Alcohol Detector with Automatic Machine Shutdown System Factory worker alcohol detector with automatic machine shutdown system is a system, that checks the worker condition constantly, either he is in drunk or normal condition if he is in drunk condition then also check the range of this drunk value if it is above the permissible range then shutdown the machine automatically with sending alert message at authorized mobile no. If we see in our industry side, then there are so many machines which are so much costly and their operating system is also so much complicated. For operating this complicated system, the worker should be in medically or mentally fit condition, otherwise a one mistake leads to a serious consequence, such as in the form of life or business loss. If anyone or factory worker take a drunk then, it directly effects on his mental condition and in this condition if he operates the machine then he would damage the machine or loss of the life. For escaping this life or business loss here we have designed a system that is called a factory worker alcohol detector with automatic machine shutdown system with the help of pic microcontroller 18F452, alcohol sensor, GSM modem, LCD display and motor. This system shutdown the machine automatically after detecting the worker drunk condition.

This sensor has very good sensitivity and fast response for alcohol detection. Motor: The working of this system is checked by connecting the dc motor at output side. Working Principle of Factory Worker Alcohol Detector with Automatic Machine Shutdown System: This factory worker alcohol detector with automatic machine shutdown system works on the principle of alcohol detection. Alcohol is detecting through the alcohol sensor, when this sensor senses the alcohol then its resistance is changed as per the concentration of alcohol, means when alcohol concentration is high then its resistance would be low and when alcohol concentration is low then its resistance would be high. Here for demonstration purposes dc motor has been used. When any drunk person takes the breath in front of alcohol sensor then alcohol sensor senses this breath and check the concentration level of alcohol if the concentration level is high then permissible level then it gives the logic high signal to microcontroller. After receiving the logic high signal, microcontroller goes into the alerting mode. In alerting mode, it turns on the buzzer for giving warning intimation and display this alert mode on LCD display. In this condition, microcontroller also gives the logic low signal to turn off the motor and gives the intimation message at authorized mobile phone through the GSM modem. So, this is the main working principle of the automatic system. Applications and Advantages of Factory Worker Alcohol Detector with Automatic Machine Shutdown System: 1. This factory worker alcohol detector with automatic machine shutdown system could be used in industries for saving human life. 2.

Vehicle Movement Based Street Light System Using PIC Microcontroller

Vehicle Movement Based Street Light System Using PIC Microcontroller Vehicle movement based street light system using pic microcontroller is a system, which turned on or off the street lights after sensing the vehicle movement in a street. Basically, this an energy conservation system which saves the energy when there is no any vehicle movement in a street. Now days if we see in our vicinity areas, then there are so many lights which are always in turned on condition (day and night). Besides this, turned on/off the street light on daily bases also a big problem. So, for resolving this problem and energy conversation here we have designed a system that is called a vehicle movement based street light system using pic microcontroller with the help of pic 18F452 microcontroller, transformer, voltage regulator and IR sensors. So many streets lights could be turned on/off automatically by using this single system. In other words, this system turned on the lights when any vehicle pass through the street and turned off after passing them.
