Question about analogue sensors on Arduino Breakout & Base Shield

[PStei3]

Hi all,

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".

Any advice?

Problem seems to be the Grove Base-Shield. Taking it out of the setup made everything work like expected ...

I have the same problem. Did you find a solution?

Only by connecting the sensors directly to the Arduino Breakout-Board.
