Measuring voltage


#1

Hi,

I have an IoT device and I would like to know how the voltage varies when there is a communication. Is it possible to do it with Otii? Which should be the assembly to do it properly? It has to be done with sense?

Thank you!

Hi,

To give you the best answer, I need to understand your set-up but yes, you can use Sense+ or/and Sense- to graph voltage.

Best regards,

I have an IoT sensor supplied by a battery:

Connecting the sense like in the image above is enough to get correct results or the setup has to be different?
I only want to measure the voltage drop when it is connecting to the network.

Hi,

I suggest something like this:

By using ADC+/- connection, you are also able to see the current consumption of your sensor.
Enable the channels ADC in current tab and ADC in voltage tab.
Size of shunt R depends on the measurement range.

Remember that AGND connection will give a GND connection to USB GND of your computer.

Best regards,
Björn
