An automated ESP32 watering system with capacitive moisture sensing, a built-in pump, and a local web dashboard. It learns your plant's rhythm — then takes care of it.
A capacitive probe sits in the soil and samples moisture every ten seconds. Air temperature, humidity, and ambient light are tracked alongside — so when your plant needs water, PlantWiser already knows.
When the soil drops below threshold, a MOSFET-driven mini pump delivers a measured dose of water — then waits a soaking period before checking again. No flooding, no guesswork. Manual override available from the dashboard at any time.
Every plant dries differently. PlantWiser observes for a few days, then automatically adjusts its watering threshold to match — not too often, not too dry. The longer it lives with your plant, the better it gets.
No accounts. No app store. No subscription. Open any browser on your home Wi-Fi and PlantWiser is there at plantwiser.local — with charts, history, settings, and a single button to water your plant manually.
Connect the device to USB power, place the soil sensor in the pot, and drop the pump tube into a water reservoir.
Join the PlantWiser setup network from your phone, pick your home WiFi, and the dashboard goes online.
For the first few days, PlantWiser learns your plant's drying rhythm and tunes its threshold automatically.
Auto-tune kicks in. Your plant gets watered exactly when it needs it. You forget you ever worried.
Hand-built ESP32 unit with OLED display, in a 3D-printed enclosure.
MOSFET-driven 5V submersible pump with silicone tubing.
Capacitive sensor — corrosion-free, with calibration baked in.
Braided power cable, 1 meter — plug into any USB charger.





plantwiser.local, and you're in. No accounts, no app store, no cloud.
PlantWiser is built by hand, in small batches, on Long Island. Every unit is soldered, tested, calibrated, and signed off by the same person who designed it. It's not the cheapest way to keep a plant alive. But it might be the most thoughtful one.
Each unit ships fully assembled, calibrated, and ready to plug in. Setup takes under five minutes.
