remote tempsensor

by cbrandy on Mon Oct 11, 2010 10:57 am

Hi. I have a arduino project, and I need some help.
My project is to controll temperature in my livingroom and bedroom. I need a temperatur sensor on the walls, which sends wierless signal to arduino board. Then the arduino board sends signal to my panel heaters.

How could I do this? What kind transmitter and receiver do I need?
From my Arduino board to sensors it might be like 10 meters.

Best,
Andy

Take a look at the xbee modules.

You will have to consider power if they are battery powered. If wall wart powered then it is not a problem.

Hi guys.
I thought of using xbee first, but then I have to use ready-made solutions.
I would like to use something that is not cooked, but to create something even then ...
I have seen this in sparkfun.com "nRF2401A".
My idea is to use something like this.

It will be used batteries to power this.

Maybe the JeeNode Kit is something for you, it's half cooked and looks interesting.
You'll get a ATmega and a RFM12B radio which is using the 433MHz band and you just need to add a temperature sensor. Such a radio might also be better in terms of battery life.
You can get it from jeelabs.org (EU) or moderndevice.com (US) and No! I don't get paid be them ;)
