9 Steps to Create a LED FSM to Measure Power with FPGA

Hi there FPGA geeks! Power monitoring is a big step when it comes to analysis and subsequent models used for power conservation. The project for today is building an FSM (finite state machine) with a LED as its output and FPGA as its core to measure the power output by the LED when it is active. The IR sensor detects motion and switches on an LED, whose power is measured by the board. This FPGA LED FSM project can be extended to real life scenarios such as measuring the power of fans and other individual electric components in the house to control and conserve power consumption.

The Hardware requirements for this miniaturized model are an IR motion sensor, a LED, a transistor, a FPGA Board and jumper wires. The black box diagram for the project is given in Step3. The wiring instructions are given in Step 8, and the description for the many modules used in this project have been given in the preceding step.

The code has been segregated into modules and has been written using VHDL (.vhd). The VHDL files are available for download from Step 5 along with the XDC master file necessary for the FPGA Board Port Map implementation, you may need to adapt this to your own needs. The code has been written in modules, and can be modified to measure power of any device connected to the board provided its consumption per second is known.

This project can only be used to measure the power consumption of a device for 15 seconds due to circuit limitations. However additional displays and clocks can be used to extend this time frame provided the code has been tweaked on properly.
