I have a problem with my project. I would like to make a wall light switch with these:
copy code remote controller → 433 Mhz el cheapo RF receiver → arduino rcswitch
I’m using 17cm antenna with the 433 mHz reciever.
I programmed the rcswitch send demo, and programmed the copy code controller. The system works well, and the reciever can detect and decode the signal.
The only problem is that it has only about 0,5 m range…
Can anybody help me how could I extend the range? (needed about 10-20 m)
Thank you all in advance!
