A soil-moisture watering system with peristaltic pump, reservoir level sensor, leak detection, local schedule and phone alerts.
A plant watering robot fails when it trusts one cheap soil sensor forever. Soil probes corrode, pots drain differently and pumps siphon if tubing is routed badly. A robust build combines moisture thresholds, dose limits and leak detection.
Use a peristaltic pump or diaphragm pump so water only moves when commanded. Add a reservoir level sensor so the pump does not run dry. For indoor plants, a leak sensor under the pot tray is more important than fancy AI.
Local schedule, Wi-Fi alerts and pump control
Less corrosion than resistive probes
Controlled dosing without siphoning
Prevents dry pump runs
Stops watering if water appears under the tray
Routes water to pots cleanly
One sensor, one pump and a small bottle reservoir.
Multiple emitters, larger reservoir and weather-resistant box.
Add ESP32-CAM for daily snapshots and growth timelapse.
Treat the generated output as a prototype plan, not a certified product. Body-adjacent, high-voltage, optical-energy and mobility builds need qualified review before real-world use.
Capacitive sensors are usually better than exposed resistive probes, but still need calibration per soil mix.
Yes. Add maximum dose per day and a leak sensor, not just a moisture threshold.
No. Keep watering local; use Wi-Fi only for alerts and logs.
