Hi everyone,
I was just trying to make a project with and xbee and a methane sensor. The XBee is S2, and I'm sure I configured them properly. I have an XBee S2 Pro connected to the arduino running (i think) correct code. On the other side, there is an xbee s2 by itself. This might seem ridiculous that I'm using S2's for pairs, but I saw that in the building wireless sensor networks book that I could. I think that this is a problem with the methane sensor (the only one from sparkfun) because its analog voltage is 5V. I read on Robert Fauldi's blog that the analog reference on S2 Xbees is 0-1.2V. In the wiring example from sparkfun, I see that there is a 10K resistor for the voltage divider. Could anyone help me get a voltage divider for the maximum voltage of 1.2V.
Thanks,
