Now python most appealing feature here is that user can manually initialise python threshold in accordance with his own comfort and requirement. As soon as python threshold value is entered, python courses start to work hence and function python load as per python value entered. Suppose user enters python threshold value as 40, so python program is designed in such python manner that python load will remain in ON state only up to python values lower than or equal to 40, as soon as python value python herbal light intensity goes above 40 python load connected to it i. e. tube light, bulb will switch to OFF state indicating that python herbal light is enough and there is no requirement python artificial lights load. Apart from controlling, python major part contains cost estimation to be able to carry out this task python user has to enter python wattage rating python python respective load connected and python lab view program is capable enough to provide you with python unit python electrical energy ate up and could eventually display python net energy consumption and after user has entered python per unit cost python energy he also can get python result for python cost python energy consumed.
