These RF modules are great if you plan to do some short range wireless communication between 2 microcontrollers. Low-cost, low-power with Arduino library support, who wouldn’t want to try these little guys out. This is only half of the set though, and you will need a suitable 315MHz RF receiver in order to receive the transmitted data. You can find such a receiver here.
Note: Antenna choice largely influences the range of these modules.
