Cargo Tamper-Evident Seal Project Kit with Arduino Nano — Logs Every Tilt with Timestamp

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Every cargo shipment faces a quiet threat — undetected tampering. With this kit, you'll build a compact, battery-powered seal that sits inside any box and records every unauthorized tilt or shake. Designed for student innovators exploring logistics security, supply chain monitoring, or Smart India Hackathon challenges, the Cargo Tamper-Evident Seal Variant 20 turns raw sensor data into a timestamped log, displayed clearly on an LCD. It's a practical project that merges hardware prototyping with real-world anti-tampering logic.

What You'll Build

You will assemble a fully functional tamper-evident seal that mimics industrial cargo monitoring devices. The ADXL345 accelerometer continuously checks orientation; any tilt beyond a set threshold increments an event counter and stamps it with the exact time from the DS3231 RTC. The current seal number and violation count appear on a 16x2 LCD. All event data persists in the Arduino Nano's EEPROM, so the log survives power loss. Use it to secure a prototype shipment, demonstrate a cold-chain integrity monitor, or integrate it into a larger IoT logistics node.

What You'll Learn

• Interfacing the ADXL345 3-axis accelerometer and calibrating tilt thresholds
• Logging timestamped events to EEPROM with DS3231 real-time clock accuracy
• Driving a 16x2 character LCD over I2C for live status readouts
• Designing a stateful tamper-detection algorithm for cargo security applications

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate project is ideal for CBSE Class 11-12 students building physics or computer science investigatory projects, B.Tech ECE/EEE learners tackling embedded security prototypes, and teams competing in Smart India Hackathon logistics or supply chain tracks. ATL Tinkering Labs and hobbyist makers from IIT, NIT, VIT, and BITS will find the tamper-logging logic a solid base for advanced cargo IoT systems.
