Solar-powered soil moisture irrigation system (Arduino/ESP32) for dry regions of Kenya - includes an offline WiFi dashboard, a grain/fodder storage humidity monitor and a Flask+SQLite backend for historical data and trend predictions. # Solar-Powered Soil Moisture Irrigation System An engineering project by a 4th year student at Murang'a University of Technology, building a low-cost, solar-powered irrigation system for dry regions of Kenya, with an offline web dashboard and a companion grain/fodder storage monitor. This project is being developed with an eye toward expansion into a future final year project. ## Problem Dry regions of Kenya (target deployment: Mbeere, Embu County) face both crop-watering scarcity and post-harvest storage losses. This project addresses both with one shared sense-decide-act architecture. ## Components - **/Solar-soil-irrigation/arduino** - Arduino Uno version: soil moisture sensor -> relay -> water pump - **/Solar-soil-irrigation/esp32** - ESP32 version: same logic, plus an offline WiFi dashboard (no internet required - connects directly to the device's own network) - **/Solar-soil-irrigation/storage-monitor** - Adapts the same architecture to monitor grain/fodder storage humidity, triggering a ventilation fan to reduce mold/aflatoxin risk - **/Solar-soil-irrigation/backend** - Flask + SQLite server for historical data logging and a simple trend-based prediction of when the next watering will be needed ## Hardware - Arduino Uno or ESP32 - Resistive soil moisture sensor - 5V relay module - Mini submersible DC pump (3-6V) - 6V solar panel, TP4056 charge controller, 18650 Li-ion battery, boost converter ## Status Prototype phase - tested in Tinkercad (Arduino) and Wokwi (ESP32). Physical hardware build in progress. ## Author Brian Gitau - Electrical/Electronics Engineering Student, 4th Year, Murang'a University of Technology
