“Measure voltage, current, active power, power factor, and electrical energy with any microcontroller through UART.
If we knew how much energy we use at each moment, I am convinced that we would use it better, just for the pleasure of seeing the consumption metrics go down.
I verified this once I installed a screen showing the energy consumption of my house in the corridor. With the fact of announcing that the number with the W next to it, the bigger it was, the more expensive the bill would be at the end of the month, I already had my family turning off things, just to see it go down.
I’ve been making videos of power meters for a while now and I set out to create a metering module that we could easily use with any microcontroller.
If you are a visual learner I know that a video is worth more than 1000 words, so here is a tutorial video. (I am a Spanish speaker, so please consider turning on English subtitles):”
