That’s actually a brilliant idea—tiny, low‑cost tech can do a lot. Just make sure the microphones are positioned where the frogs actually vocalize, and use a good low‑frequency filter so you’re not picking up wind or traffic. The temperature log will help correlate call frequency with microclimate shifts. If you add a small camera with infrared, you could also catch the little salamanders you love. Just keep the software tidy; I’ll bet you can script it to auto‑tag species and timestamps. Keep me posted on how the data streams come in—I’m eager to see what patterns emerge.
