Problems when sending float (temperatur) with VirtualWire Arduino
// 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)
#include "DHT.h"
#include <VirtualWire.h> // you must download and install the VirtualWire.h to your hardware/libraries folder
#define DHTPIN 4 // what pin we're connected to
#define DHTTYPE DHT11 // DHT 11
#undef int
#undef abs
