Story
This project is a fully automated AI-powered greenhouse control system built using the Elecrow ESP32-S3 Advance 7" Display Module. It combines real-time environmental monitoring, automated device control, and smart decision-making to maintain optimal conditions for plant growth.
With features like touchscreen control, Wi-Fi connectivity, and modular code design, this system makes it easy to manage your greenhouse from anywhere. It’s a great example of how modern microcontrollers can be used for smart farming and sustainable agriculture.

🔧 Introduction, Features & Design
The core of this project is the Elecrow ESP32-S3 Advance 7", a powerful development board featuring:
-
A 7-inch 800x480 capacitive touchscreen
-
ESP32-S3-WROOM-1 with dual-core processor, Wi-Fi, Bluetooth 5.0, and AI acceleration
-
Built-in speaker, microSD slot, USB-C, RGB LED, and buzzer
-
Support for LoRa, LVGL, Arduino IDE, and ESP-IDF
This touchscreen not only displays the system dashboard but also provides direct interaction for controlling greenhouse operations.
🌿 Main Functions of the Greenhouse System
-
Real-Time Monitoring
The system displays live sensor data for:-
Air humidity and temperature
-
Soil moisture
-
pH levels
-
Water tank level
-
-
Automatic Actuator Control
Based on sensor inputs, it automatically operates:-
Drip irrigation pump
-
Misters
-
Exhaust fan
-
Grow lights
-
Water refill pump
-
-
Manual Overrides & Touch UI
Users can override automation and control each actuator directly using the touchscreen. -
-
AI Integration
AI logic (leveraging ESP32-S3’s AI acceleration) helps optimize irrigation and climate management based on trends and past behavior. -
Settings Panel
A full-featured settings screen allows users to:-
Configure Wi-Fi
-
Switch between auto/manual modes
-
Adjust automation thresholds
-
Save preferences
-
-
Future LoRa Expansion
LoRa modules will soon allow wireless communication with remote sensors and actuators—ideal for large or distant greenhouses.
💻 Program and Code
The project is developed using the Arduino IDE, and the UI is built with the LVGL graphics library. The code is cleanly structured in modular files, separating:
-
UI components
-
Sensor handling
-
Automation logic
-
Device control
-
Wi-Fi and settings management
This makes it easy to expand or customize the system for different greenhouse setups.
Some highlights of the programming approach include:
-
Event-driven button handling for manual control
-
Periodic sensor updates with data filtering
-
EEPROM or SPIFFS for saving user preferences
-
Use of timers for actuator cooldowns or cycling
-
Planned integration of AI inference for smarter decisions
The code is fully commented and designed with clarity for both beginners and advanced users.
