Hack Your Home Part 3: Power Monitor

In addition to controlling appliances, we can also measure how much power they are using. In this episode, you will use a CT sensor to measure the current being drawn by an appliance and post that data to the Internet. Note that a little bit of math is necessary to figure out the average current.

Brilliant ! I thought of using this concept on a dust collection automation system I am working on. You proved me it should work. I thought of doing the exact same way as you did. Thanks for sharing this

[@ericsumma7654]

If both hot and neutral wires are fed through at the same time, any ground fault would provide an output. However it might be more accurate to have separate current sensors on each wire and then use an op amp circuit to subtract the two, aka diy GFI measurements.

This is a great explanation, thank you!

Pretty good! Took me hours reading same info which is condensed here

[@gginnj]

What adjustments would need to be done if the sensor cable were plugged into a 25 foot extension cable?

[@Golkun1]

Why not using two 220 Ohm resistors in parallel to get the 110 Ohm burden resistor value?

[@TushhsuT]

because at the end it can be easily corrected by a scaling factor in a program.

[@Golkun1]

@@TushhsuT and this can't be done with the 110Ohm resistor? Please explain in more detail why this isn't possible in your opinion.

Is it okay if the audio jack not connected onto a breakout board?

[@TheUnofficialMaker]

yes

[@rp4881]

Noted. Thank u😊
