Advanced Grain Bin Temperature Logging Kit (Arduino Mega & DS18B20)
Grain Bin Hot Spot Monitor Kit with Arduino Mega & DS18B20 Probes - Multi-Sensor Data Logging
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Spoilage in stored grain often begins as an undetected hot spot deep inside the bin. With this advanced kit, you'll build a field-ready monitor that reads six depth temperature points and two air humidity zones, logging every reading to microSD for trend analysis. Use it to protect real grain stores or prototype a precision agriculture sensor network.
What You'll Build
A complete data logger that displays real-time temperature gradients on a 0.96-inch OLED and saves timestamped records to a microSD card. You'll install six waterproof DS18B20 probes at varying depths, two DHT22 sensors for ambient air data, and a DS3231 real-time clock - creating a system that mimics professional grain storage monitoring setups.
What You'll Learn
- Multiplexing and addressing up to six one-wire temperature sensors on the Arduino Mega.
- Real-time data logging to microSD with precise timestamps from the DS3231 RTC.
- Interfacing an OLED display for live sensor readings and system status.
- Soldering and assembling a rugged sensor board on prototype PCB.

Who This Kit Is For
This kit is designed for B.Tech ECE/EEE students building agricultural IoT projects, participants in the Smart India Hackathon, and final-year engineering students from institutions like IIT, NIT, VIT, or BITS who need a working prototype for precision farming. CBSE Class 11-12 students with strong Arduino experience and ATL tinkering lab mentors will also find it a powerful hands-on challenge.
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 to open the AI companion, trained on this specific wiring and code. It can guide you through every connection and troubleshooting step. If you need human help, message us on WhatsApp - we reply within working hours.
Can this monitor be used for server rooms as well?
Yes, the same sensor array works perfectly for server rack temperature mapping. Place the DS18B20 probes near exhaust vents or between racks, and let the system log temperature trends with timestamps. You only need a different enclosure.
Will the probes survive in dusty grain environments?
The DS18B20 probes are sealed in stainless steel and rated for immersion; they handle grain dust and physical contact without issues. Protect the PCB with a simple enclosure and use silicone sealant at cable entry points.
Does the kit include ready-to-use code?
The AI companion delivers Arduino code pre-validated for this exact component combination. It handles one-wire addressing for all six probes, SD card file management, RTC synchronization, and OLED updates - you can modify the temperature thresholds easily.
Data Centre - Six DS18B20 probes at different depths + DHT22 at air level detect hot spots in stored grain bin.
