본 제품은 434MHz 무선 수신 모듈로 약 장애물이 없는 공간에서 최대 150m 거리까지 통신이 가능합니다. (대기중의 습도를 감안하면 이보다는 짧을 수 있습니다) 아두이노 라이브러리를 사용하여 어렵지 않게 무선 통신이 가미된 프로젝트를 구현할 수 있습니다.

Description: These wireless transmitters work with our 434MHz receivers. They can easily fit 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 communicating data one-way, 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 at common frequencies and don’t have IDs. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link.

Note: Color may be blue or green, but they are the same module.
