Reading analog voltage on Xbee from lm34 temperature sensor

Hey everyone,

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

The max voltage of an S2C if I recall is 0 - 1.2V for analog.

You are also causing a dead short by connecting VCC to GND.
