I have 3 analogue sensors ( like this one http://www.ebay.com/itm/171705525756 Soil Moisture Sensor Hygrometer Detection Module for Arduino | eBay ) connected to the ports A0 - A3 on my Base Shield ( Seeed's Grove Starter Kit ).
The sensors have an LED showing a certain humidity level.
My problem now is, that whatever I do, all three sensors react when one of them gets in contact with humidity, but I can only get proper readings from the one connected to A0 if the Base Shield.
Are the A0 - A3 inputs not separated from each other, or is my general understanding of this analogue ports wrong?
Any advice is highly appreciated
I forgot to mention, that I'm using Node-Red on the Edison and am accessing the GPIOs via mmra ( http://flows.nodered.org/node/node-red-node-intel-gpio Library - Node-RED ).
I have now investigated that whatever I use as pin is define in the node-setting, he always seems to read from the one in slot "A0".
