The project titled “Digital Watt Meter with Individual Load Measurement” is designed to measure and display the power consumption of different electrical loads such as DC motors and LED units individually. The system uses voltage sensors to continuously monitor the electrical parameters of each load and sends the measured data to a PIC microcontroller for processing and analysis. The microcontroller calculates the power consumption of the connected loads and displays the individual readings on an LCD screen through an LCD driver circuit. A regulated power supply is used to provide stable operation of the system, while a crystal oscillator ensures accurate timing control. LED indicators and switches are included for status indication and load control. This project provides an efficient, accurate, and low-cost solution for monitoring power usage in electrical and electronic applications, helping users analyze energy consumption and improve power management.      

The main objectives of the project are:

  To design a digital watt meter for measuring individual load power consumption.

  To monitor the power usage of DC motor and LED units separately.

  To display voltage and power readings on an LCD display.
