Frost Alert Kit with Arduino
Frost Protection Alert Kit with Arduino Uno & LED - Shield Your Seedlings from Sudden 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.
Indian winters can arrive suddenly, dropping soil temperatures below 2�C and wiping out tender seedlings overnight. With this kit, you'll assemble a real-time ground frost alert system that sounds a buzzer the moment frost risk hits-giving you time to cover your plants or move pots indoors. It's a hands-on way to learn Arduino programming while solving a genuine agriculture problem.
What You'll Build
A working frost monitoring device with a waterproof DS18B20 probe that reads soil temperature accurately. When the temperature falls below the 2�C threshold, a red LED flashes and an active buzzer sounds an alert. A 16x2 LCD display shows the current temperature and alert status, so you can monitor from a distance. The entire circuit runs on a 9V battery, making it portable for your kitchen garden or nursery.
What You'll Learn
- Interface a DS18B20 digital temperature sensor with Arduino Uno
- Write code to set threshold conditions and trigger alerts
- Display real-time sensor data on a 16x2 LCD using I2C communication
- Integrate LEDs and a buzzer to create a multi-sensory alarm system

Who This Kit Is For
Perfect for CBSE Class 6-10 students exploring smart farming for their science exhibition, or ATL Tinkering Labs running IoT-in-agriculture modules. B.Tech agriculture or ECE freshers can use it as a mini-project foundation. Even young terrace gardeners (with elder guidance) can set it up to guard their coriander and tomato seedlings during December-January chills.
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 AI companion walks you through every connection and line of code; if you still need help, WhatsApp message us-our engineers respond within hours.
Can the sensor be placed directly in soil?
Yes, the DS18B20 comes in a waterproof stainless steel housing, so you can bury it a few centimeters deep to measure root-zone temperature safely.
Will this work for a school science exhibition on smart agriculture?
Absolutely. The real-time LCD display and audible alarm make the frost effect dramatic and easy for judges to understand. You can also extend the code to log data.
How long does the 9V battery last?
With the LCD backlight on, a standard alkaline 9V battery powers the system for roughly 6-8 hours of continuous use. For extended monitoring, swap to a rechargeable battery or USB power bank.
DS18B20 ground temperature probe triggers buzzer when below 2�C frost risk threshold. Protects seedlings.
