I’m putting together a personal smart-irrigation setup and need a complete working design that I can assemble at home. The core of the system will rely on: • Soil moisture sensors, temperature sensors, and a rainfall sensor for real-time environmental data • A water flow sensor and water dispenser to manage delivery • An Arduino for low-level sensor handling and control signals • A Raspberry Pi for data logging, dashboards, and remote alerts Here’s what I’m looking for: 1. Wiring diagram and parts list showing exactly how the sensors, Arduino, Pi, and pumping hardware connect. 2. Firmware/sketch for the Arduino that reads each sensor, drives the pump or valve, and communicates with the Pi (I’m comfortable flashing the board myself). 3. Python (or Node-RED) scripts for the Raspberry Pi that store readings, push notifications to my phone/email when thresholds hit, and expose a simple web dashboard. 4. Clear setup instructions so someone with moderate maker experience can replicate the build without guesswork. Accuracy and reliability matter more than fancy UI—robust sensor calibration routines and safe pump control logic are key acceptance criteria. If you have prior projects using similar hardware, a quick demo video or repo link would help me gauge fit.
