plant-monitoring-system
@rojar2006

This project is a compact, low-power smart plant monitoring system designed using KiCAD. It integrates an ESP32-C3-WROOM microcontroller with a range of sensors and peripheral interfaces to monitor soil moisture, temperature, and humidity. The system is ideal for IoT-based plant care, home automation, or educational prototyping.
