Review on π DIKAVS 5Pcs 3-24V Small Enclosed Piezo Electronic Buzzer Alarm 95DB w/Wires: Compact and Loud Device for Versatile Applications by John Jones
All 5 worked, the audio output was slightly different but the same.
One day I will measure the output signal in dB but the description seems accurate at 9 VDC. They are very oriented and have less free space per db than, for example, when mounted on a countertop or a slab. So far I'm happy with the value for money. Will be upgraded after being used in car headlight monitor with zero temperature F for durability.
- Everything is fine!
- Expensive
