Industrial Boiler Temp Monitor Kit with Arduino Mega + Relay
Industrial Boiler Temp Monitor Kit with Arduino Mega + Relay: Automate pH, Temperature & Light Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a fully automated environmental controller for smart farming or industrial process monitoring. This Arduino Mega-powered kit enables you to manage fish tank heaters, grow bed pumps, pH dosing systems, and grow lights on a schedule, using real-time sensor data from temperature, pH, brightness, and an RTC. Perfect for B.Tech projects, hydroponics enthusiasts, or anyone tackling Smart India Hackathon challenges.
What You'll Build
A complete 4-channel relay control system that reads two DS18B20 temperature sensors, an analog pH probe, and a BH1750 light sensor, then drives actuators based on user-defined thresholds and a real-time clock schedule. You'll solder and assemble a custom PCB, connect an OLED display for status, and calibrate the pH module for precise dosing.
What You'll Learn
- Integrating multiple I2C and one-wire sensors with Arduino Mega and managing bus conflicts.
- Using an RTC module to trigger scheduled events for pumps, lights, and heaters.
- Soldering through-hole components and assembling a prototype PCB into a durable enclosure-ready board.
- Programming relay logic with hysteresis to prevent rapid cycling of pumps and heaters.

Who This Kit Is For
This kit is designed for advanced learners—B.Tech ECE/EEE students, VIT/NIT/IIT final-year project builders, and participants in Smart India Hackathon. It's also ideal for agriculture-tech innovators setting up automated aquaponic or greenhouse systems in Indian conditions, where reliable temperature and pH control is critical.
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?
The kit includes a QR code to your AI build companion, which has been trained on this exact project's code, wiring, and calibration steps. You can also reach our WhatsApp support for direct help.
Is soldering required, and do I need prior experience?
Yes, you'll need to solder components like resistors, capacitors, diodes, and headers onto the PCB prototype board. The kit includes a soldering iron and solder wire, and the AI companion provides a video guide for beginners.
Can I expand this system to control more than 4 devices?
The included 4-channel relay module provides four isolated outputs for heater, pump, dosing unit, and light. You can cascade additional relay modules using the Mega's spare digital pins, or adapt the code for I2C relay expanders—detailed as an advanced challenge in the companion.
What kind of pH calibration is required?
The analog pH module requires two-point calibration using buffer solutions (not included). The AI companion guides you through the procedure with code snippets, and the OLED displays live pH values for fine-tuning.
Industrial Process — Controls fish tank heater, grow bed pump, pH dosing, grow light via relays based on pH, temp and RTC schedule.
