Project Help and Ideas » WattMeter (Volt x Amp)

Hello, Do you have any idea how Volt, Amp and (V*A=W)Watt Could be measured a Motor while driven controlled by our MCU? I found some Current sensors just like temperature sensors. But For Voltage measuring I could not find something like that. Is there any one has better idea? B. Regards Serkan |

If it is a DC voltage motor: Use a current shunt and measure the voltage across it using an opamp instrumentation preamp. This will be your current to voltage converter. Plug that into a ADC. |
