This is the Seeedstudio 315MHz RF Low Cost Transmitter/Receiver Pair. This kit is consisted of transmitter and receiver, popularly used for remote control.

Usage:
The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU.

The PT2262 (Encoder) and PT2272 (Decoder) are optional, their existence is to (1) avoid confusing when multiple RF links in range (2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both sides. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.

At 9 VDC input the communication range is approximately 300 m to 500 m in open air.
