How We Tracked Mine Trucks and Fuel Levels Using LoRaWAN Sensors

In mining operations, the biggest issue isn’t the number of trucks it’s the lack of real-time visibility. Inside mines, trucks move through harsh routes, blind turns, and heavy operational zones where managers often don’t know which truck is where, how long it has been idle, or whether it is running efficiently.

At the same time, fuel becomes another silent challenge. Without continuous fuel level tracking, small losses, inaccurate refueling logs, and sudden drops go unnoticed until they impact production. The result is a mix of delays, inefficient dispatch, unplanned maintenance, and low fleet productivity all because critical truck data stays trapped inside the vehicle and never reaches the decision-makers.

To eliminate blind spots in mining fleet operations, Macnman deployed MacSync series IoT nodes on trucks, leveraging existing RS485/Analog sensors. This setup enabled real-time location tracking, performance monitoring, and automated reporting, all without disrupting existing infrastructure.

Deploying inside a mine is never like deploying in a factory or office. Everything is metal-heavy, routes keep changing, and signal conditions can break normal wireless systems in minutes. That’s why this project started with one priority: make LoRaWAN communication reliable inside the mine, not just “working on paper”.

We installed MacSync LoRaWAN IoT nodes on the trucks and connected them directly to the existing RS485 fuel level and vehicle sensors, so the mine didn’t need to replace proven hardware. Once the truck data started flowing, we brought it into a single monitoring layer where the operations team could see truck movement, fuel trends, and performance signals in real time. The end result was a deployment that felt simple to use but underneath, it delivered the most important thing mining teams need: visibility and control inside a harsh environment.
