Real-world applications

Example projects showing what this product can read, control and report. Each requires the appropriate sensors, connected equipment and application software.

Delivery vehicle tracking

Example: read GPS positions while a delivery van is travelling and upload location updates over 4G. A fleet dashboard can plot the route; microSD logging keeps a local trip record when coverage is unavailable.

Vehicle maintenance monitoring

Example: read permitted operating values from a compatible vehicle CAN network using the correct message definitions. Firmware records abnormal values and sends them to a maintenance dashboard for review.

Construction asset tracking

Example: fit the controller to a mobile service vehicle or powered asset. A location application compares GPS readings with an assigned site boundary and reports arrivals or departures over the cellular link.
