🌊 Smart Aquarium V2.0 🐠

🎛️ IoT-Based Aquarium Automation System

Control your aquarium using a web interface!

⚠️ CAUTION: This project involves working with electrical components and may require handling of high voltage connections. Always prioritize safety, use proper insulation, and consult with a qualified electrician if you're unsure about any aspect of the installation or operation.

📢 Development Notice: This project will no longer receive feature updates. A new NodeMCU 12E (ESP8266) version: Smart Aquarium V3.1 is ready & ESP32 version: Smart Aquarium V4.0 is under development that supports more powerful customization options and advanced monitoring features for aquarium inhabitants. Be the first ones to try it out and give feedbacks! 🚀

📥 Installation

# Clone this repository
git clone https://github.com/desifish/Smart-Aquarium-V2.0.git

# Navigate to the directory
cd Smart-Aquarium-V2.0

# Open in Arduino IDE
# Update WiFi credentials in aqua_NODEMCU.ino
# Flash to NodeMCU

Important: The favicon image inside the data folder needs to be copied into the flash storage of the NodeMCU. This ensures the web interface can properly display the favicon. For instructions on how to upload files to the ESP8266 filesystem using LittleFS, please refer to this updated guide.
