These wireless transmitters work with our 433MHz receivers. They can fit easily into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work by communicating data in one direction; you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.
Note:These modules are indiscriminate and will receive a fair amount of noise. Both the transmitter and receiver work on common frequencies and do not have an ID. Therefore, a method will be needed to filter this noise and pair the transmitter and receiver. The following example code shows an example of basic operation. Please see the example code and links below for ways to achieve a robust wireless data link.
