I want to get the current as high as the water heater so I guess that's around 60A. Regarding the microcontroller, I am not allowed to used Arduino (By the way, it is now a team project)
I added some modifications to my initial plan. Instead of just the ampere value, I will also display the waveform for each breaker/appliance real-time, store/send the data on internet and the data can be retrieved from home owner's cellphone. So my main design components are
Non-Invasive Current Sensing --> Analog to Digital Conversion --> Microcontroller --> Mobile (Android) App
I just thought that when measuring the signal then converting it to digital signal, I might encounter a lot of noise. I would like to know how can I minimize the noise? What type of circuit I can build to handle this?
