Arduino Boiler Temp Monitor Kit - DS18B20 & RTC Timer for Showers
Industrial Boiler Temp Monitor Plus Kit - Arduino-Powered RTC Timer and Temperature Control for Showers
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
What if your morning shower water was perfectly heated, ready exactly when you needed it-without wasting electricity all night? This intermediate kit guides you through building a microcontroller-based system that uses a DS18B20 temperature sensor and a DS3231 real-time clock to trigger a relay, switching a heater (like a boiler or geyser element) on and off according to a programmable schedule. Think of it as a smart timer for any water-heating appliance, teachable in ATL tinkering labs or B.Tech ECE projects.
What You'll Build
You'll create a fully functional prototype that monitors water temperature in real time, displays it on an LCD, and automatically activates a relay at the time you set-like 30 minutes before your shower. The unit logs the schedule via the RTC and uses push buttons to adjust the setpoint, so you never step into a cold bath again.
What You'll Learn
- Interfacing a DS18B20 digital temperature sensor over 1-Wire protocol
- Using a DS3231 RTC module to trigger events at specific times
- Controlling a high-current relay safely with an Arduino Uno via a transistor/diode snubber
- Displaying real-time information on a 16x2 LCD with I2C backpack and reading button inputs

Who This Kit Is For
This kit is designed for intermediate learners aged 15-18, especially CBSE Class 11-12 students building physics or computer science projects, B.Tech ECE/EEE undergraduates exploring industrial automation, and ATL tinkering lab mentors demonstrating real-world IoT. It also serves as a solid base for Smart India Hackathon prototypes where timed control of any appliance is required.
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?
Open the AI companion via the QR code on the box-it walks you through wiring, code, and debugging for this exact kit. You can also message us on WhatsApp for human support.
Can I directly connect this kit to a household geyser?
No-this kit is a low-voltage prototype using a 5V relay. Connecting to mains AC (230V) requires proper isolation and safety measures; we recommend demonstrating the concept with an LED or small DC load. You can later scale the design with an SSR and electrician supervision.
How does the RTC keep time when the Arduino is off?
The DS3231 module includes a CR2032 battery backup, so it continues tracking date and time even when unpowered. When the Arduino powers back on, the code reads the accurate time from the RTC immediately.
Can I change the temperature setpoint without reprogramming?
Yes-the three tactile buttons on the breadboard let you adjust the target temperature and schedule directly through the LCD menu interface, no USB connection needed after initial upload.
