Hello everyone.

I'm starting my project that consists in a GSM/GPRS module that controls the flow of energy in a circuit.

My idea is to use a GSM/GPRS with integrated microcontroller module, connected to a second module, a energy meter (in my case CS5463). This 2 modules would connect with each other via SPI interface.

My problem now is to start building the energy meter circuit, should i use the example in the energy meter IC datasheet ou start from scratch and use a current and a voltage transducer?

The power line here is 220V.

Thanks in advance

Hi I would like to know a bit more about what kind of control you will have on the flow of energy. I saw the CS5463 circuit and I think is perfect for metering but not to control. Best regards.

Hi.

The control i want to do is realy simple actualy. I just want to start and stop the energy flow (based on SMS received by the GSM/GPRS module). But at the same time i need to do the metering, to know V, I, etc..

I recommend Figure 19. Typical Connection Diagram (Single-phase, 2-wire – Isolated from Power Line). Is the most safe one. And what uC and GSM/GPRS modem you are using?

Good Luck!

Maybe a PIC16F877A, or a gsm/gprs development board, like olimex PIC-GSM...

Hi.

I was planning on doing something similar to your project.

I want to use a GSM device to act like a switch when it receives a SMS, and measure the charge of a electric car, using an energy analyser, in my case a CS5463.

Is it plausible to measure the charging process of an electric car using the CS5463?
