A system includes a longitudinal rack storing a plurality of items, a shoe movably attached to the rack, a magnet coupled to the shoe and a longitudinal circuit board arranged along the length of the rack. The circuit board includes an array of sensors along the length of the rack. Each sensor generates a voltage value depending on a position of the magnet in relation to the sensor. The circuit board further includes a memory storing voltage values generated by the sensors, and a processor configured to monitor voltage values generated by the sensors, detect that a particular sensor has generated a maximum voltage value and determine a number of items stored in the rack based at least in part upon a particular number of items corresponding to the particular sensor.

The seed counting sensor (200) for pneumatic seeding machines comprises a detection chamber (210) within a house (204), said detection chamber allowing the seeds to pass through the sensor and having a center axis (211) extending in the flow direction of the seeds (102); a plurality of light sources (240) arranged within the house (204), outside the detection chamber (210), at predetermined distances from each other, said light sources being in a plane (P) extending substantially perpendicularly to said center axis of the sensor; a plurality of light detectors (250) arranged within the house (204), outside the detection chamber (210) at predetermined distances from each other, said light detectors being in the same plane (P) as the light sources, wherein the number of the light detectors equals to the number of the light sources, and a signal processing unit (502) for controlling operation of the light sources (240) and for processing the electronic signals produced by the light detectors (250).

A conveyor element (2) of a conveyor device conveys bar-shaped products (1) orthogonal to a longitudinal direction (x) of the bar-shaped products (1) oriented in a conveying direction (y). A trigger device (3) provides a trigger signal (S) each time the conveyor element (2) has travelled a predetermined interval. Based upon the respective trigger signal (S), an image (B) is acquired by a camera (4). The image (B) shows front ends of the products (1) in a respective section of the conveyor element (2) corresponding at least to the predetermined interval. Based upon the acquired images (B), the number of bar-shaped products (1) conveyed by the conveyor element (2) is determined.
