使用rpirf_接收器时，433Mhz上出现意外的消息量

Question

我想清理一下我的家庭自动化装置，意识到我有433MHz的接收机和发射机，还有一个旧的覆盆子Pi 1（B）

我将接收器连接到5V、GND和GPIO 14上的数据，然后运行rpi-rf_receive -g 14。我正要按下433MHz遥控器上的一些按钮，它就开始打印了

我还是按了一下按钮，但在连续不断的“消息”流中，我无法识别任何额外的信息。这是噪音吗？我住在一个别墅区，但最近的房子大约20米远。我有一些温度和湿度传感器（4），但我的印象是它们不会连续发送。此外，价值观似乎无处不在

我不知道这应该是什么样子。这方面的所有指南都非常干净，不必担心其他传入数据。有人能辨别出我接收到的是什么，还是仅仅是噪音

谢谢
