Hi another ADS1115 question please.
(And it's not on an Arduino but on a Pi Zero 2W thru an HW-660 Pi Hat/Board with an ADS1115 attached. See: https://www.aliexpress.us/item/3256803757799407.html?gatewayAdapt=glo2usa4itemAdapt)
I'm playing with two types of Hall Effect current sensors, a WCS1600 and an ACS712.
All current sensors boards do not have their DC current terminals wired up. They're just reading "nothing".
With an Winson WCS1600 current sensor attached only to Channel 0 (3.3V and Ground attached) I get these readings:
raw v
11774 1.470
11775 1.470
An ADC value of about 11775 and a 1.47V reading.
Then I left the WCS1600 attached and added an ACS712 30A current sensor to Channel 1.
And these are the new readings:
raw 0 v raw 1 v
14170 1.770 6079 0.636
14170 1.770 6059 0.640
14170 1.770 6060 0.640
14170 1.770 6057 0.642
The WCS1600 ADC values and voltages jump up a bit.
Now leave the WCS1600, the ACS712 30A connected and add a WCS712 5A current sensor to Channel 2:
raw 0 v raw 1 v raw 2 v
14169 1.770 6068 0.638 4543 0.586
14170 1.770 6069 0.642 4589 0.566
14170 1.770 6056 0.642 4638 0.574
My question is - could someone explain to this non-EE type why the WCS1600 readings went from 11775 to 14170?
I'm not that concerned about this, I'm just curious as to why the value would jump up?
Again, there's no DC current flowing thru the sensors, they're just sitting on my desktop wired to the ACS1115.
thanks!
