| 09 dec 2020 20:16:13 | Arduino wattmeter | Janjos | Hi, I adapted the Arduino watt meter code so it runs on a UNO. For those that want to try it before building it, the code can also be tested using SimulIDE (www.simulide.com), together with a ready to use simulation circuit that I draw. Am I allowed to post both files, .ino and .simu, here ? If yes how ? Best wishes, Janjos |

| 30 nov 2020 07:35:05 | Fast Lux meter | hgg2k | Hi, the OSRAM BPW34 has a listed 80nA/Lx sensitivity. Does this make ~10 times more sensitive to low light than the BPW21? Thanks. |

| 24 sep 2020 09:20:35 | Arduino wattmeter | Guenter2 | Doh, that did not occur to me, it's an AC wattmeter, of course it can measure negative voltages - oh well, feeling pretty dumb now! ;-) \\ Very cool, that little wattmeter is exactly what i needed, thanks for sharing!\\ Best regards,\\ Guenter |
| 24 sep 2020 09:04:09 | Arduino wattmeter | Freddy | You don't have to modify the circuit. The wattmeter can measure negative voltages. Connect the current measure side so it measures also negative. The result is a positive power measurement. |
| 23 sep 2020 21:10:31 | Arduino wattmeter | Guenter | Hi Freddy, cool project! I have a question - i need to measure the current on the high side of the load - how would i have to alter the circuit to implement this? I thought of disconnecting the common lead from the voltage measurement part of the circuit, and providing the 0.55V offset (half of the reference voltage) for the positive input of the opamp with its own resistor divider. The voltage measurement would stay the same - except it has no common connection to the current shunt. Does that make any sense? Could that work this way? Thanks, Guenter |

I have cleaned the UI a bit, leaving only the application for learners to practice. I also have given credit to you with a direct link to your site. |
