Aquarium Automation Kit with ESP32 and Telegram Bot Control
Aquarium Auto Controller Pro Kit: ESP32-Powered Telegram Bot for Your Aquarium
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine walking into the room and finding your aquarium heater stuck on, risking your fish. Or leaving home without turning off the lights. With this kit, you build a Telegram bot that lets you send commands like /pump_on and /led_off directly from your phone, and get a confirmation reply in seconds. The ESP32 connects to your Wi-Fi, listens to the bot, and controls a relay that can switch real aquarium equipment—all while you learn the fundamentals of IoT automation.
What You'll Build
You'll assemble a functional IoT aquarium controller on a breadboard. Connect the relay to control a pump, heater, or light (up to 10A @ 230V AC), wire the LEDs as status indicators, and program the ESP32 to respond to custom Telegram commands. The bot replies with “Pump ON” or “LED OFF” messages, confirming your command was received. You’ll end up with a project you can mount in your aquarium cabinet to automate daily routines.
What You'll Learn
- Programming an ESP32 to connect to Wi-Fi and use the Telegram Bot API for two-way messaging.
- Wiring a 5V relay module safely with a 1N4007 flyback diode to prevent voltage spikes.
- Debugging IoT code using the Arduino Serial Monitor and understanding HTTP/HTTPS protocols.
- Building a real-world automation system that reacts to remote commands without any port forwarding.

Who This Kit Is For
Perfect for school students in ATL Tinkering Labs who want to explore IoT, CBSE Class 11-12 learners working on practical electronics projects, and B.Tech ECE/EEE first-years needing a hands-on automation demo. It’s also ideal for Smart India Hackathon participants building assistive control systems and young makers at home who want to automate a fish tank light or filter with parental guidance.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with your AI companion, which has the complete circuit diagram, code walkthrough, and troubleshooting steps. You can also reach live support through WhatsApp on weekdays.
Can I control a real 230V aquarium heater with this relay?
Yes. The 5V relay module is rated for 10A 250V AC. Wire the live wire through the COM and NO terminals (using proper insulation) and always test the circuit unplugged first. The included 1N4007 diodes protect the ESP32 from back EMF.
Do I need a static IP or port forwarding to use the Telegram bot?
No. The ESP32 uses Telegram’s polling method—it checks for new messages every few seconds. Just connect to a stable Wi‑Fi network and start chatting with your bot. All communication stays inside Telegram’s secure servers.
What happens if the Wi‑Fi disconnects while the relay is on?
The relay will maintain its last state (on or off) until power is cycled or the ESP32 reconnects and receives a new command. You can add a watchdog timer in your code to turn off the relay after a timeout for extra safety.
Aquarium Automation — ESP32 Telegram bot receives on and off messages and controls relay or LED. Replies with confirmation.
