Later, as the third part by the analog signal from the measuring voltage and current compared เฟสก it to determine the different phases of the signal cable.The fourth part is the analog signal from the measurement voltage. Current and the phase difference between voltage and current process in micro controller, and calculate the voltage, electric current. The power factorThen, the microcontroller will take from time to time comparisons module base the use of electric equipment and electric power, the electricity used to compute current. Electricity daily, monthly electricity bills.Part five is the values calculated to show results through the screen LCD Part VI is the values ที่คำนวณ passing through wireless network, in which this research use. XBee Module to send and receive data to the computer.Microsoft Visual Studio 2012 language Visual C # on programming data to collect data in the form Database which was connected to the program. Access which is a program to collect data in the form Database n.XBee Module receiver and to bring information to display screen, program storage. Then the program data to save the data into the Database every time input, and can open the view data in Database history.
