Plant Environment Monitor

Designed and built a single-board plant monitoring system using an Arduino UNO R3 to track key environmental variables affecting plant health. The system reads temperature and humidity via a DHT11 sensor, ambient light intensity via a photoresistor voltage divider, and displays all readings in real time on an LCD1602.

A millis()-based timer tracks the watering interval and sends an alert on the display when watering is due. A physical button logs each watering event and resets the countdown. Firmware was written in C++ using the Arduino IDE with the Adafruit DHT and LiquidCrystal libraries.

Planned expansions include telemetry for monitoring data analysis and in Excel, and an automated watering system driven by a soil moisture sensor and pump, and profiles for different plants to minimize the need for human input.
