That’s a solid start. Put a 12‑volt solar panel on a 12‑volt charge controller with a Li‑Po battery so you never have to touch the station when it’s dark. Run an ESP32 or a low‑power Arduino Nano 33 BLE for the brain – it’s small, eats little juice, and has Wi‑Fi or BLE built in. For the “quiet” part, use passive infrared (PIR) sensors that only wake the microcontroller when something crosses the beam. Keep the enclosure camouflaged and put the PIR modules on a low‑profile tripod so the animal doesn’t notice them. Log the data on a microSD card and then sleep the ESP32 for a few minutes until the next trigger. If you need to pull the data off the ground, add a small LoRa or Sigfox module instead of Wi‑Fi – they’re designed for long‑range, low‑power. And if you want a touch of “real” animal feedback, mount a tiny speaker that only blares a soft chirp when an animal is detected – not loud enough to scare them, just enough to tell you something’s around. Just keep the whole thing under a watt or two and you’re good to go.
