IoT Fleet Management & Telematics
Key Business Outcomes
Zero Spoilage
Completely eliminated cargo loss due to temperature failures in the first year of operation.
12% Fuel Savings
Achieved by identifying and training drivers with harsh acceleration habits via AI scorecards.
Automated IFTA
Saved 40 hours of administrative work monthly by automating IFTA fuel tax calculations from GPS data.
The Challenge
Our client, a national cold-chain logistics provider operating a fleet of 500 refrigerated trucks, was facing catastrophic revenue losses due to cargo spoilage. They were relying on outdated GPS trackers that only pinged location every 15 minutes and provided zero visibility into the actual temperature of the refrigerated trailers.
If a trailer's refrigeration unit (reefer) failed in the middle of a 12-hour haul across the desert, the driver often wouldn't know until they opened the doors at the destination, resulting in $100,000+ of spoiled pharmaceuticals or food per incident. Furthermore, they had no automated way to track fuel theft, which was quietly draining their margins.
Our Technical Solution
Vanavya Tech replaced their fragmented tracking system with a unified, custom IoT Fleet Management Platform.
We integrated directly with advanced OBD-II telematics devices and Bluetooth Low Energy (BLE) temperature sensors installed inside the trailers. Using the ultra-fast MQTT protocol, the trucks now stream thousands of data points per second (GPS location, engine RPM, fuel level, and trailer temperature) directly to our custom cloud platform.
We built a real-time alerting engine using Apache Kafka and TimescaleDB. If the temperature in a trailer carrying vaccines rises by even 1°C outside the safe zone, the system instantly triggers an automated SMS and automated phone call to both the driver and the central dispatcher, allowing them to route the truck to an emergency repair facility before the cargo spoils.

Technical FAQs
How did you handle vehicles driving into cellular dead zones?
We utilized an edge-computing strategy on the hardware. The IoT devices are programmed to cache the telemetry data locally on their internal memory when they lose cellular connection. The moment the truck regains 4G service, the device bulk-uploads the historical data with precise timestamps, ensuring the database has a perfect, unbroken breadcrumb trail.
Why did you use TimescaleDB instead of standard PostgreSQL?
A fleet of 500 trucks pinging multiple data points every second generates billions of rows of data very quickly. Standard relational databases choke on this volume. TimescaleDB is a time-series extension for PostgreSQL that automatically partitions data by time, allowing us to query millions of GPS pings in milliseconds for the dispatcher dashboard.
