I am new to these forums and relatively new to Arduino (have been playing around with blinking LEDs, a toy car that stops according to a distance sensor, etc.)
I would like to build a system that monitors the temperature in 3-4 rooms indoors in my house, as well as outdoors.
The plan in my head right now is to have "satellite" Arduinos, or perhaps stripped-down Arduino-like microcontroller devices, each bearing an LM35 temperature sensor or something similar, transmitting temperature information wirelessly every 1-10 minutes to some kind of central or "base station" Arduino, which then can display all 4-5 temperatures on a screen.
Future projects could involve dumping the temperature vs. time data to a file for later analysis, or turn the data somehow into a Web page.
The tricky part of this for me is choosing how to communicate the data from the "satellites" to the "base station".
There are a lot of sample projects out there but some are a few years old, and with lots of devices and libraries out there, I'm unsure about what the best implementation is today (late 2014).
I would ideally want a wireless solution that is fairly inexpensive, relatively easy to code for and can handle the multiple inputs.
Your help is greatly appreciated!
