 Overview

 The 433MHz RF link kit is consisting of one transmitter and one receiver, popular use for remote control.

 

 Specifications

Receiving frequency: 433.92Mhz;   operating voltage DC5V;     reception sensitivity: 105DB
Modulation: ASK;     size: 30 * 14 * 7mm
Receiver Data Output: High - 1/2 Vcc, Low - 0.7v
Transmitor Input Voltage: 3-12V (high voltage = more transmitting power)

Hardware

There are one transmitter and one receiver in this kit. You will needs 2 Arduino main boards in your application: one for coding and sending the message, with the RF transmitter, the other one for receiving the message and  decoding. The whole system is working as belows:  

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 sides. Whenever there is no 433Mhz devices around, you may use it as direct cable connection.
