ABSTRACT:
The present invention provides an automatic detecting device for radio frequency environment used to detect radio frequency noise. The device uses an antenna to receive radio frequency noise and the radio frequency noise is passing a radio frequency comparator and transformed into a voltage signal. Then, the voltage signal passes through an amplifier and is amplified to be an output voltage. If the output voltage exceeds a threshold voltage, it drives a post stage circuit to warn when the radio frequency noise is beyond a normal value.
