RF Module signal is too weak
I am trying to build an arduino RF remote control to clone my remote control for my wireless sockets.
I bought this RF module from ebay
At first I thought it was damaged because I wasn't getting any signal from the reciever. After many tries I touched the reciever with the remote and suddenly I got the codes (I want to recieve the codes, save them and then re-transmit them with the arduino). The same goes with the transmitter - the only way it works is when I hold it against my wireless socket. It means that the codes work but the signal is way too weak.
I tried hooking it up to different power sources- Arduino 5V, Arduino 3V, 12V 1000mA Adapter, and the original battery of the remote that states 12V 23A.
I tried making an antenna but nothing really works..
please help! thank you..
