I'm using an XBee S2 module for sampling from three analog sensors; I have linked them to AD0,AD1 and AD2 and I send the values from this node (Router/end Device) to a Coordinator node. This works properly.
My question is:
is possible to link these three sensors to the same power supply of the xbee? into the same circuit?
My problem is that if the value of a sensor changes, this affect the value of the other sensors, and this is not good.
I'm using a brightness sensor (LDR) a temperature sensor (LM35) and a moisture sensor.
Is the circuit the problem or other Xbee module problem that I don't know?
