The hardware stack includes an Adafruit Capacitive Soil Moisture Sensor, an Unexpected Maker Feather S3 microcontroller, and a custom 3D-printed enclosure to house the electronics. Together, these components collect and transmit reliable soil and temperature data while keeping the setup neat and protected.

Firmware is written in CircuitPython, and sensor data is sent to the Adafruit IO cloud platform for real-time visualization. Users can view soil moisture levels, temperature trends, and Wi-Fi signal strength through a clean dashboard interface. The system makes it easy to monitor multiple plants and quickly detect when adjustments are needed.

This project demonstrates practical applications of maker electronics and IoT technology. It is ideal for automated garden monitoring, alerting when plants require watering, or collecting data to optimize care routines. It also highlights the process of hardware debugging, calibration, and enclosure design, giving students hands-on experience in a full-stack IoT solution.
