analog input resolution 30%erro - jltluc57 - 01-19-2025
Hello
Can you tell me the resolution on the analog inputs.
Because for 1.5v in I visualize 2.01v which is 30% error..
That's a lot
Board A16

I watched the video, but I don't use Home Assistant.
And that doesn't solve the problem.
In any case if I put 1.5 volts on the analog input, in the Monitor part of the KC868_A16 card, I should see 1.5V and not 2.01Volts.
ADC is in the A16 card in any case the displayed value must be correct.
Whatever the system that will read the value, it must be correct at the source therefore KC868_A16.
You don't agree?

Hi,
Here
RE: analog input resolution 30%erro - admin - 01-26-2025
the battery “-” have connected with board's power supply's GND?
do you want to monitor a battery voltage?
RE: analog input resolution 30%erro - jltluc57 - 01-27-2025
Yes the gnd is connected
Look at the photos of the posts
I test the capacities, reliability, etc of the card before buying others.
There I am on the analog inputs and I look at the reliability of the measurement, I send 1.5v I see that I have 2.01 volts so problem
there is a problem.
