Automatic cooling unit is a system typically delivers a controlled amount of coolant to specific locations on a machine while the machine is operating, at specific times from a central location. When the temperature at the work piece is increased above the reference temperature.
Automatic Traffic Signal Controller was made up with AT89s51 Microcontroller. As the number of roads users constantly increase and resources provided limited, Automatic Traffic Signal Controller is major Requirement.
This project is based on the automatic liquid filling in the object like glass, bottle, cup etc. This
can do all in time duration, which is stored in microcontroller.
Here the water pump and motor gets the signal from the microcontroller through the relay
driver circuit. Microcontroller takes the signal from its sensors.
