I'm currently working on a project that involves me making a small and simple bat detector using the Arduino.
Basically, what I'm attempting to do is have a device that can be placed outside, which records sounds at the Ultrasonic frequency range, this is then recorded to a MIcro USB device in the .wav format. It does not really need to do any complex processing, if any at all. Just the basic requirements of recording. I've been looking at getting this shield from Adafruit:
Would this therefore be compatible in recording at the frequency that I want? Also, there is another problem in choosing the right microphone/sensor in order to record at such frequencies. I don't want to use a USB microphone, I know there are such products out there, instead what I want to do is actually create this onto a bread-board where hopefully, in the future this can be soldiered permanently. In the mean time, this is just for prototyping purposes.
Does anyone have any recommendations? Both of the shield from Adafruits and the sensor that I should/could use.
