GreensKeeper: Automated Plant Care
Timeline: April – May 2025 (Senior Design Project)
Tech Stack: Raspberry Pi, Python (Flask, OpenCV, APScheduler), PCA9685, ADS1115, Peristaltic Pump, 3D-printed hardware
Overview
GreensKeeper is a smart plant shelf designed to automate watering, lighting, and monitoring for houseplants. Built on a Raspberry Pi with Python control scripts and a Flask web interface, it provides real-time soil moisture sensing, pump activation, and dimmable LED grow lights — all viewable and controllable from a local web dashboard.
