First Claim
1. A system for measuring weight on a trailer of a vehicle, the system comprising:
- a sensor system comprising a plurality of sensors, wherein each sensor is attached to an axle of the trailer or the vehicle;
a microcontroller for receiving a transmission of strain change from a sensor and for calculating the weight on the trailer; and
a display unit for displaying from the microcontroller a calculated weight on the trailer.

Abstract
A system and method that can provide a measurement of the weight on a trailer or vehicle, e.g., a truck or rig. The system and method can be implemented on systems that are equipped with air suspension, as well as those without air suspension, unlike conventional systems that require air suspension systems for installation. Additionally, the system and method can yield gross trailer weight, even if the truck is not instrumented. Further, the system and method can provide axle weight on properly equipped axles. A system for measuring weight on a trailer of a vehicle has a sensor system having a plurality of sensors, wherein each sensor is attached to an axle of the trailer or the vehicle. A microcontroller receives a transmission of strain change from a sensor. A display unit displays a calculated weight on the trailer from the microcontroller.
