An apparatus and method for measuring the weight of a moving object is disclosed. In one embodiment, the apparatus includes a platform for supporting the moving object to be weighed, means for permitting the object to move smoothly over the platform, a weight sensor for measuring a force applied to the platform by the moving object and generating a weight sample that reflects the measured force value, a detection sensor that generates a signal upon detecting the moving object on the platform, a processor having a memory, which processor receives samples from the weight sensor and stores weight values based on the samples; and means for calculating the weight of the object using a succession of the stored values when the detection sensor generates its signal. In one embodiment, the means for permitting the object to move smoothly over the platform comprises a set of rollers provided on the platform, in another embodiment, the means for permitting the object to move smoothly over the platform comprises wheels on the object. In one embodiment, the method of weighing the moving object, includes the steps of: (a) moving the object to be weighed over a weighing platform; (b) sampling the value of a weight sensor which senses a load applied to the platform by the object as the object moves over the platform, the sampling being at a rate sufficient to ensure a succession of samples taken during a period of time when the object is supported by the platform; (c) storing each of the succession of samples in a buffer; (d) receiving a signal from a sensor indicating that the moving object has reached the end of the platform and in this way sufficient samples have been stored; and (e) calculating the weight of the object based on the succession of samples.
