433 Mhz RF Transmitter and Receiver Module for Wireless Remote Control

The 433MHz RF link kit is consisted of transmitter and receiver, popular used for remote control.
Features
Frequency: 433Mhz
Modulation: ASK
Receiver Data Output: High - 1/2 Vcc, Low - 0.7v
Transmitor Input Voltage: 3-12V (high voltage = more transmitting power)
Transmitting range (at 5V): 40m indoor, and 100m in open air
The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU
PT2272(Encoder) and PT2262(Decoder) are optional, their existence is to avoid confusing when multiple RF links in range isolate disturbance.You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 433Mhz devices around, you may use it as direct cable connection.
