This is an interesting implementation of Arduino and Wireless comunication. The user [priyansmurarka] posted:
Ok, so here is the basic problem statement. I need to develop a temperature sensing system such that the temperature from the sensor node is relayed to a co-ordinator sensor and then the co-ordinator node shows the user in a simple graphical form.
For the wireless communication, I used Xbee Series 2 modules with Arduino Board Shields.
Uses Melexis Temperature sensor and Arduino Board to monitor and plot ambient temperature.
The realization of this project is well documented on the [blog], with code, graphs and pictures.
