I am looking advice to design smart power consumption monitoring system. I want to design a system that will measure the power consumption of device such as light bulb, Fan, cooler etc and It will store the record of power consumption into database server so we can monitor the electricity usage of each devices
I have searched on internet and I found that raspberry pi can be use in this project. I think have to use ADC chip but don't know others
I don’t have idea how raspberry pi measure power consumption. I mean which circuit or sensor require to design system.
I am looking advice to design system. Do I need sensors to measure power consumption of devices ? What circuit do I need to measure power consumption of each devices?
