Industrial Boiler Temp Monitor Kit v3
Industrial Boiler Temp Monitor Kit v3 — Real-Time Water Quality & Control with Raspberry Pi Pico W
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 hardened industrial process monitor that reads boiler water temperature, pH, total dissolved solids, and electrical conductivity — then triggers pumps, heaters, and aerators automatically while pushing live data to any MQTT broker. Designed for final‑year engineering prototypes and industrial IoT skill development, this kit turns a Pico W into a central controller that mimics real plant‑floor logic.
What You'll Build
You will assemble a fully functional water quality monitoring and relay control station. The 0.96‑inch OLED displays real‑time temperature, pH, and TDS readings. Two waterproof DS18B20 probes measure inlet and outlet temperatures, the pH module and TDS EC meter track water chemistry, and the 4‑channel relay board drives actual actuators. MQTT over Wi‑Fi pushes data to Node‑RED, AWS IoT Core, or a local dashboard — exactly what industry expects from a smart boiler system.
What You'll Learn
- Calibrate analog pH and TDS sensors against standard buffer solutions and known EC values
- Implement MQTT publish/subscribe on the Pico W for cloud‑connected boiler telemetry
- Design relay‑side isolation and logic to safely switch external heater, pump, and aerator loads
- Create a custom OLED‑based field dashboard using MicroPython and I2C for instant operator feedback

Who This Kit Is For
B.Tech ECE, EEE, and Mechanical engineering students in their final year will find this kit directly aligned with IoT‑based industrial automation capstone projects. ATL Tinkering Labs and Smart India Hackathon teams tackling process control or water quality challenges can rapidly prototype on a single breadboard. Researchers and industrial training centres exploring MQTT‑driven SCADA‑like data pipelines will also benefit from the pre‑verified sensor‑to‑cloud stack.
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 included in the box to start a chat with the AI companion, which has been trained on every wiring detail and calibration step of this kit. You can also reach Compoden support on WhatsApp for a direct human follow‑up within working hours.
Can this kit monitor an actual industrial boiler directly?
The sensors and relays are designed for prototype‑scale water tanks and small process vessels. They demonstrate industrial principles but should not be directly wired to high‑pressure boilers without proper isolation, enclosures, and certification.
Is the MQTT setup compatible with free cloud platforms?
Yes, the Pico W can connect to any standard MQTT broker including Mosquitto, HiveMQ Cloud free tier, and AWS IoT Core. The AI companion includes sample code for a secure Wi‑Fi + TLS connection and a raw data topic structure you can plug into Node‑RED or Grafana.
What calibration fluids or tools will I need separately?
You will need pH 4.0 and 7.0 buffer solutions for the pH module, plus a conductivity standard (e.g., 1413 µS/cm) for the TDS meter. A multimeter is helpful but not mandatory; the AI companion guides you through a software‑only calibration routine using known solution values.
Industrial Process — Pico W reads DS18B20 water temp, DO, pH and EC. Controls heater, pump and aerator relays with MQTT reporting.
