Abstract

A dispensing system is a system designed to respond to the user’s instruction to dispense the liquid. This paper discusses an automatic dispensing system with a biometric security system such as a finger print analyzer. The finger print analyzer checks the authorization of the person who wishes to access the liquid. As many harmful chemicals are used in industries today, it should be kept protected for safety issues. Auto guided vehicles such as a line follower robot can be used to take the vehicle to the place where the liquid is needed. Now the user gives the amount of liquid needed. This information is given to the micro controller which uses the fuzzy logic algorithm to decide how long the solenoid valve should be open. If the level of water in the tank of the dispenser is more, the pressure of liquid coming through the valve is more and vice versa. Now the database collects all the information as to which user accessed how much amount of liquid at what time. This information is stored in a weekly and daily basis for ease of the viewer in a GUI (Graphical user interface). The administrator of this system can be given the authority to authorize any other persons to access the liquid in the system. These systems can be used in industries were harmful chemicals that cannot be touched by human beings are used.
