Microprocessor based centralized control equipment of energy conservation:
The sensors are employed to get the values/levels of quantities to be controlled like intensity of light, speed of machine, temperature etc. These sensors may be for position, temperature, light etc. The signals from the sensors are converted to digital form and fed to the microprocessor, which determines the requisite actions needed for implementing energy conservation settings by fetching data for comparison from the ROM and carrying out internal actions for decision making by calculations/comparison using the RAM. The requisite signals are given to the control gear for controlling loads.
