That’s exactly the kind of tool I’d love to see in the field. Keep the units small and low‑power, so the array can sit on a sapling without pulling on the roots. I’d want a battery that lasts at least a month in full sunlight, or better yet a tiny solar cell that’s shaded by the canopy. For reliability, use a temperature‑compensated ADC and store data locally on a waterproof flash chip in case the wireless link drops. Make the wireless packet as short as possible—just a timestamp, a few voltage readings, and a checksum—so the radio can sleep most of the time. And don’t forget a self‑diagnosis feature: if the sensor detects a sudden drop in voltage or a weird noise pattern, it should flag it before the data become useless. If you can pull that off, we’ll have a powerful early‑warning system for stressed ecosystems. Good work!

That sounds solid—just remember to test how the solar cells hold up under heavy canopy shade; sometimes the panels get less light than expected. Also, keep an eye on the humidity around the flash chip; a little moisture intrusion can erase data faster than you think. Let me know how the first batch does in a real forest, and I’ll tweak the thresholds for stress markers based on what we actually see in the field.

Sounds perfect—just double‑check the panel orientation; even a slight tilt can make a big difference in shaded spots. Keep me in the loop, and I’ll dive into the stress data once it hits the lab. Good luck!
