Soil Health Monitor

Overview

This project uses an array of sensors to collect data like moisture, temperature, and light intensity to measure soil conditions. We envisioned this project as part of a Smart Home system, where this data would be sent through the cloud and accessed anywhere.

Description

We wanted to create a gardening system that monitors soil and alerts its users when it becomes unhealthy. It takes in data from sensors (primarily humidity and temperature) and distributes it into a cloud for users to view. We are using a battery to power the PCB, but in a realistic setting, we would use solar power and a battery storage system for self-sufficiency.
