Additional Information [Hide]

Not so much interested in data transfer as simple, non-critical remote operation system? This 315MHz transmitter/receiver pair from Seeedstudio fits the bill!

Specifications:

  • Frequency: 315Mhz.
  • Modulation: ASK
  • Working voltage: 3-12VDC(Transmitter), 5VDC(Receiver)
  • Receiver sensibility: -105dbm
  • Emission distance: 100m in open ground

Warning: Not suitable for data transfer; just simple remote control, 2 commands per 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 5VDC, 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.
