Review on πŸ”” Yohii Electronic Buzzer Alarm Beep Buzzer - Pack of 3, 85dB Sound, DC 9-15V by Christopher Buck

Revainrating 5 out of 5

Loud pulsing alarm As it should be

There is nothing more to say. It's difficult to find a piezo that doesn't produce a continuous tone. They are "active" which means they have a pulse circuit built in.

Pros
  • Model: HYD-4218, Voltage: 9-15V DC; Rated Current: 12mA; Frequency: 4000Β±500Hz; Noise: 85 dB
Cons
  • Negative impression
