Review on WEICHUANG Active Electronic Buzzer Continous by Adam Ross

Revainrating 5 out of 5

Loud enough for horns and sirens

Connected to a test lamp I use on airplanes so I don't have to bend down to see the light. This is a 28V DC system so I soldered a 1kΩ resistor in series to drop the voltage. Works perfectly. Similar to the diode on your Fluke test tool, only louder.

Pros
  • SOUND OUTPUT: The horn is 100dB at 12V DC at 30cm, you can wait for your desired volume by adjusting the voltage. Response Frequency: 3 ± 500 Hz
Cons
  • Something else

these are not bad but just not very loud.
