Industrial Boiler Temp Monitor Kit with Arduino Uno + DS18B20
Industrial Boiler Temp Monitor Kit with Arduino Uno & DS18B20 — Shield Your Plants from Frost
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Frost can destroy a season's worth of seedlings in a single night. This kit puts a rugged waterproof temperature probe right into your soil, using an Arduino Uno to read its digital data. When the temperature drops below a threshold you set, a loud active buzzer and dual red LEDs flash an immediate warning — giving you time to cover delicate plants before damage sets in.
What You'll Build
A self-contained temperature alert station that runs on a 9V battery. The DS18B20 probe is IP68-rated, so you can bury it directly in a garden bed, greenhouse, or raised planter. The Arduino continuously compares the live temperature against a safe minimum, and if frost danger is detected, the buzzer sounds and the LEDs blink urgently. No internet or phone needed — it works right in the field.
What You'll Learn
- Connecting one‑wire digital sensors to an Arduino Uno
- Reading and calibrating DS18B20 temperature data for outdoor use
- Programming conditional thresholds and alarm triggers in the Arduino IDE
- Assembling a portable, battery‑powered monitoring circuit on a breadboard

Who This Kit Is For
CBSE Class 11-12 students building agriculture or physics projects, B.Tech ECE/EEE learners exploring sensor networks, and Smart India Hackathon teams that need a rapid frost-alert prototype. ATL Tinkering Labs and hobbyist gardeners in India will appreciate a ready‑to‑build solution that avoids hunting for compatible sensors, cables, and resistors across multiple shops.
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 inside the box to open the AI companion. It walks you through every connection and code line — plus you can message us on WhatsApp for a human backup.
Can the DS18B20 probe handle wet soil and rain?
Yes, the probe head is fully sealed with IP68 waterproofing. You can bury it in moist garden soil or leave it out in a greenhouse without fear of water damage.
Can I change the temperature at which the alarm sounds?
Absolutely. The Arduino code makes it easy to set your own frost threshold. The AI companion shows you exactly where to change a single number to trigger the alert at 2°C, 0°C, or any other temperature.
How long will the 9V battery last in the field?
With a fresh 9V battery and the alarm triggering only occasionally, you can expect 2–3 days of continuous monitoring. For longer deployment, you can easily swap to a 9V rechargeable or a USB power
