Loud buzzer for industrial environment


Can you please advise if you knew of a buzzer/speaker that is really loud enough and yet small (4cm radius & 2.5cm height max) to get the attention of anyone working in a very noisy environment like the packing area (machine noise and everything) of a warehouse? I will be putting this on into a raspberry pi project that I have built, so power from GPIO or a step-up module will be considered.

Thank you!

Kind regards,

Hi Allan,

Sounds like you’re after a Piezo buzzer. If you try searching for ‘piezo’ you can find all of the related products, and just find the biggest one available that suits your requirements.
