Re: counter

Counter --> POWER METER ???

Accurate power meters are not easy to build; have a look at this project: https://www.analog.com/UploadedFiles/Application_Notes/528608457AN641_0.pdf

However, if you would like to roughly estimate power drawn by your houshold you can construct this simple circuit: **broken link removed** , and replace 100µA meter with an equivalent load and then ADC-->microcontroller-->digital display ..

Regards,
IanP

Unless you are suitably qualified you should seek professional advise before messing with mains wiring.

Start by reading the old threads in this forum. there have been a load of threads about measuring the power equipment is drawing from the mains such as **broken link removed**. Use the search.
