VCC voltage module operating voltage and good power filtering;
A great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, generally a 50 ohm single-core wire, the length of the antenna 315M approximately 23cm
Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.
The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU
PT2272(Encoder) and PT2262(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 side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.
