Many times, employees have a drink and come to the workplace which inturn causes lots of inconvenience to other employees. In this project 'Workplace Alcohol Detector With Instant Reporting', the system is used to instantly detect if any employee comes drunk at a workplace.
So for this purpose we use a PIC microcontroller which consists of alcohol detector, LCD display, buzzer and LED. We can also send SMS notification via GSM modem.
The entire system is powered by a 12V power supply. The system constantly monitors for any alcohol present nearby. As soon as alcohol is detected at the sensor, it produces an equivalent voltage and signals the microcontroller. The microcontroller on reading the signal instantly goes into alert mode.
The system now displays the status of the event occurred on an LCD display, also sounds a buzzer to alert. It now uses the GSM modem to send an SMS message to the user/authority to inform about the situation so required action can be taken for it.
