Im thinking of using a radio transmitter reciever pair from sparkfun to transmit sensor data wirelessly. Any one have any ideas. I have the book making things talk. But theres not enough about radio transmitter reciever pair.

You might want to look at VirtualWire.

Thanks for posting your experience, I've been suggesting VirtualWire to people based pretty much purely on the the apparent quality of the documentation so it's nice to know it works well.

Hi

VirtualWire is excellent and I have got the example transmit tx / Receive rx circuit working well, but I have tried to adapt the code to transmit a temperature reading from a Dallas 18B20. If I comment out the dallas code the Virtual wire works fine (Transmitting OK to the receiver), and if I comment out the VirtualWire the Dallas code works fine (reading Temperatures), but together I get wrong readings from the Dallas (E.g. 58C or -212C etc), which is connected to Pin 6.

it seems to be this line corrupting the temperature readings:

vw_send((uint8_t *)msg, strlen(msg));

Am I missing something?

Any ideas?

Thanks
