I have a question regarding reading analog voltage on the Xbee from lm34 temperature sensor.
I connected the circuit as such:
**In the diagram I accidentally connected the GND pin of LM34 to VCC
My problem is that as soon as I connect the Xbee to the breakout board, the temperature readings on the Arduino increase. At room temperature I measured the output voltage of the lm34 to be 0.7V but as soon as I connect the Xbee, the output voltage of the lm34 rises to 2V.
I know normally lm34 is connected to 5V VCC but I read that Xbee analog pins take a max of 3.3V.
I am using Xbee S2C, any ideas as to why this is happening?
**The problem seems to go away when I connect the analog input to pin AD0 instead of AD3
