I would like to share my code. With this code your Arduino tells you by RF Link if your room is too cold or too warm. You need 2 Arduino's.
It is just a part of a bigger project. But you can modify the code and make some great stuff. If their are some questions feel free to ask. RF link is amazing.
// Tested with IDE 20 and VirtualWire 1.4, only working with those. // RF Link using VirtualWire to Transmit messages // simplex (one-way) receiver with a 315MHz RF Link Transmitter module // tx pin 3 on Duemilanova (arduino) //vw_setup(300)&n
I would like to use a code for sending the temperatur and humidity. One day before, I started with sending just a short message like: LMR is cool. TX= Transmitter RX=Reciever
It only worked when I used:
Arduino IDE 020 and VirtualWire 1.10 for RX
and Arduino IDE 020 and VirtualWire 1.10 for TX.
When I use Arduino IDE 1.0.3 and VirtualWire 1.4 for RX
and Arduino IDE 1.0.3 and VirtualWire (VW) 1.4 for TX it didn't.

#define DHTPIN 4 // what pin we're connected to
#define DHTTYPE DHT11 // DHT 11
