BLE Buzzer goes fishing

BLE Buzzer for Salmon evaluationI built a special version of the BLE Buzzer on request of a Norwegian customer. The buzzer is waterproof according to IP67. This was required to enable the buzzer to survive classification of salmons on board a research vessle.

It was a challenge to fit all components into the original waterproof buzzer case. I also had to fit a watertight USB charging socket, a status LED and a power switch into the housing to be able to operate the buzzer without opening the sealed housing.

The first batch successfully passed an intense testphase in a rough seawater environment.

The Buzzer Module is available in a new Version!

I updated the hardware base for my buzzer module. Using a dedicated PCB, the board now has a USB-C connector for charging, a status-LED and a push-button for switching the module on and off. The processor module supports Bluetooth BLE as well as WIFI. This allowed me to add configuration through a browser.

The module is significantly smaller than the predecessor. Therefore, it is more flexible in its appplication. It is ideal for integration in DIY buzzer projects. there are nearly no limits to phantasy when creating fancy buzzers.
