"Efficiency starts with knowledge"

And to take control of our energy usage, we need to build a power meter

Welcome back my friends

In this video, we'll build a power meter using CADIO, allowing us to monitor home AC power with high accuracy and a simple setup

We’ll be able to measure AC voltage, current, and total power consumption, all in real time

We’ll use the PZEM004T. a high-accuracy power meter module.

This module features RX and TX pins for data transfer to the ESP

It comes with a clip-on CT sensor. allowing non-intrusive current measurement by simply clamping around a live wire, with no cutting required.

Wiring is simple

Connect RX and TX to two GPIOs, we’ll use GPIO 4 and 5.

VCC to VCC

GND to GND

AC input to AC terminals

And finally, clamp the sensor around the hot wire of the load you want to measure.

In the info file, we add a PZEM004T device

and select the RX and TX GPIOs.

Our power meter will appear in the app interface, displaying the live power in watts

And when we click on it, it will display all the data

Measurements here are frequently updated every 5 seconds. we can see the voltage. The current. The real and the apparent power. The power factor, and the frequency. And our total consumption.

The consumption is stored on the module itself, and you can reset it anytime using the reset button.
