This is my midterm that I wanted to make look sleek and polished like some of the passed ones I drew inspiration from when I went back and look at some of as well as the ones my instructor showed me
The system centers around two key sensors—the SEEED soil moisture probe and the BME280 environmental sensor—which continuously track the plant’s conditions. Their data is displayed on a compact OLED screen and published to an Adafruit.io dashboard. From there, I can monitor moisture, temperature, humidity, and pressure from anywhere, and even trigger manual watering through a dashboard button.
To automate watering safely, I designed a control stage using a 2N3906 transistor driving a relay, which activates a small pump for a precise 0.5-second burst whenever the soil becomes too dry. This prevents overwatering while keeping the plant consistently healthy. I also integrated Zapier to send email alerts, making the system more responsive and user-friendly.
Building the physical structure was another part of the challenge—finding a compact way to house the plant, pump, tubing, sensors, and electronics. After several layout tests, I created a clean, stable setup that keeps everything organized and easy to maintain.
