About

In this post, I will show my DIY power/power factor meter. The module itself was bought(of course) I just put it in an enclosure and added some cables to make measurements easier. This way I have a handy and cheap tool for measuring the power and power factor of any device that I connect to it. This thing is no professional instrument with great accuracy but it’s good enough for doing some basic measurements.

Hardware used:

Making It:

The device is very easy to make. 

First I drilled two holes for the cables and cut out the top of the project box to the size required for the display.

Next, I inserted the cables into the box, crimped some connectors on the wires and connected them according to the schematic on the back of the power meter module. Zip ties were put on both sides of the cables to prevent them from sliding in and out. 

Finally, I assembled the box, pressed in the power meter module and put a socket on to the end of the output cable.

Using It:

Just plug in the power meter and connect your load. The display should show the voltage, current, frequency, power factor, current power and power used so far.
