This 315MHz RF transmitter/receiver set is a simple 100M remote-operation control link
Not so much interested in data transfer as simple, non-critical remote operation system? This 315MHz transmitter/receiver pair from Seeedstudio fits the bill!
Warning: this kit is not suitable for data transfer but remote control. Safe for 2 commands/second.
There is a "pairing" feature where you can set an 8-bit code on each side that locks the two together.
Please refer to the simple drawing (image #4) for the 315Mhz RF link. On the transmitter side, You would need to supply 3-5VDC to the "+12V" pin,(Caution: the 12v is an error silk screen on PCB, never give it more than 5Vï¼‰, and set "TE" high(5V) to enable transmission. On the receiver side, you may use +5VDC(aka VCC) for power and read the output from D0~D3. "TV" will indicate whenever there is changed data incoming.
