On the link you can see some photos of the case and internal apparatus that I made to micromoth. I used 5 of it in the Atlantic Forest of Brazil, near to caiman nests. It worked very well, but you need to take care of the acoustic membrane, as it was placed outside the case, it is very sensitive to physical damage. I used a small container made of glass and plastic cover (with latches), with sponge to fill the space, li-on rechargeable battery (6800 mAh and 8800 mAh 3.7v), memory card 64 Gb, tampon (reduce the humidity), acoustic membrane. https://www.openacousticdevices.info/support/enclosures/anyone-used-the-audiomoth-devices-inside-in-crocodilian-nest-mound-or-sand

The forum is so important.... some questions have already been answered for me now. Thanks!!

@Alex Rogers Thanks Alex. Do you have some idea how long the batteries (for µMoth) recommended (Sparkfun) could support?

@Alex Rogers Hi Alex, The µMoth can record the same range frequency of audiomouth?

Do you still have it?

I have another question that is not clear for me... What is the range of frequency recorded by the audiomoth? Crocodilians have range frequency between 400Hz and 20KHz... Is it feasible to use the equipment to record in this frequency range?

Hi Xoan, Did you get to making recordings in your research between 20Hz to 20kHz?? I also need to record between this rate. What settings did you use?
