This article describes a microcontroller Based automatic bottle filling system which senses the presence of bottle and level of liquid in it and than fills it accordingly up to a fixed level. In this project, the infrared proximity sensors are used for detecting the presence of the bottle and LDR and voltage comparators are used for sensing the level of liquid in the bottle. Fuzzy logic is used for controlling the filling of the liquid in the bottle. sample input to the computer is provided by the microcontroller . The control signal for solenoid tap is generated by the matlab program taking the sample input from the microcontroller as the input.
The block diagram of the system consists of the PC, MAX232, microcontroller 89c51, level sensor, proximity sensor, solenoid valve, bottle filling machine.
Description of Microcontroller
The microcontroller used for the project is AT89C52 which is a low-power, high performance 8 bit microcontroller. Atmel s high-density nonvolatile memory technology goes into the manufacture of this device.It is compatible with the industry-standard 80C51 instruction set and pinout.
