First, the component selection C1 selects the leakage current to be particularly small; the relay selects the small reed relay with working voltage ≤6V, pull-in current ≤15mA, contact voltage >220V, contact current >0.1A; resistance R1<500kΩ. Second, the working principle When using, press the recorder recording button, K1 closes, and put the words "The owner is not at home, please ring the doorbell, and there is something for you to record for two minutes" on the door. If you find that the LED light is on, it means that the guest has come, rewind the recording, you can know the guest message, but don't forget to break K1 once, otherwise the LED light will always be on.
