The refrigerated truck left the depot at 3 AM. The temperature sensor flagged at 4:15. Nobody knew whether the sensor was live and reporting, or whether it had never been activated on that unit. The tracker log shows the truck's position. It doesn't show what's happening inside.
Fleet-level sensor management fails when the question "which vehicles have which sensors installed and active?" can't be answered in under sixty seconds.
The Sensor Audit Is the Core Use Case
The template captures five sensor categories per vehicle: Fuel Monitoring, Temperature Sensor, Container Sensor, Mic, and Engine/ACC cut off. Each is a separate field — installed, active, and confirmed.
Fuel Sensor and Container Sensor appear twice in the field list — once as an installation flag and once as a separate confirmation field. That duplication reflects a real operational state: a sensor can be physically installed but not yet activated in the telematics platform. The two fields distinguish hardware presence from software activation, which are often handled by different teams on different timelines.
ACC status and Engine/ACC cut off together document remote immobilization capability. ACC cut-off (Accessory Circuit cut-off) is the kill switch that allows remote engine disable — relevant for recovery operations and for high-value cargo security protocols. Knowing which vehicles in a fleet have this capability and whether it's currently in the armed or bypassed state is the difference between a functional security protocol and a paper one.
Temperature Sensor is the compliance field for cold chain transport. In pharmaceutical and food logistics, the temperature sensor status is part of the delivery documentation. A vehicle dispatched for chilled cargo without a confirmed active temperature sensor is a regulatory and liability exposure.
The Financial Architecture
Tracker Amount, Per Year, and Total Amount document the telematics subscription cost per vehicle. Fleet managers buying tracking services across a mixed fleet of 40 vehicles — different makes, different sensor packages, different contract dates — often lose visibility into the total per-unit cost when contracts are managed individually.
The financial fields in this record create a per-vehicle cost baseline. Combined across the fleet, they produce the actual telematics line item for budget planning — not the quoted package rate, but the real cost including all sensor subscriptions per unit, annualized.
Vehicle Tonnage, Vehicle Make, Vehicle Model, Vehicle Number, and Vehicle Type are the identification fields that connect the sensor record to the physical asset. Driver Name and mobile number link to the current assigned operator. Owner Name, Email, and Transport Name handle the fleet owner or transport company details in multi-operator environments where a tracking service provider manages sensors across multiple clients.
The Signature field closes the record as an acceptance confirmation — the driver or owner acknowledging the sensor installation and the tracking terms on that specific vehicle.
