Yes,this is a piezo-electric MEMS microphone directly in the water. and i will put the AudioMoth in a watertight enclosure, put the microphone directly in the water through cable penetrator for ROV.
That’s great. They were £25 each last time I checked but now seem to be down to £1. They are also supposed to be much more uniform in their response - less variability across manufacture.
Brilliant. Can you post some details of the modification that you've made.

What depth are you deploying it at?
About 2 meters!
Hello qdxiatao,
Can you share some more results?
Did you protect the piezo hole or it gets in direct contact with water?
How did it perform?
Thanks,
Tim
Did you put it in salt water? It is ok for the microphone?
Any Update?
