The invention relates to a system (100) and a method (200) for measuring the filling level of a silo (110) for storing and mixing at least one bulk material, the silo being provided with a plurality of support legs (111) on the ground. The system comprises: a single deformation sensor (120) provided to be fixed to a single support leg of the silo so that the deformation sensor can detect deformations of the support leg in order to generate at least one measurement signal which comprises the deformation values, a first wireless communication means (130) provided to transmit the measurement signal, and a remote server (140) which comprises a second wireless communication means and a processor, the processor being provided to process the measurement signal so as to obtain an estimation of the filling level of the silo.

Embodiments of the present disclosure relate to apparatus for measuring various characteristics of an indoor agriculture system. In one embodiment, a plug holder weight measurement system includes a plant plug holder disposed in a grow tower and one or more load cells positioned and configured to detect a weight of a plug holder. The load cells may be compression-type, tension-type, torsion-type, or beam-type load cells and each may be integrated into the grow tower.

A load sensing system having at least one load sensing assembly for use with a weigh frame, each assembly including at least a first lever and a second lever. Each lever has a lever longitudinal axis, a lever fulcrum section, a lever load section, and a lever connector section spaced from the lever fulcrum section and the lever load section along the lever longitudinal axis. For each lever, a flexure plate is aligned in parallel with the lever longitudinal axis and has a middle bearing portion and opposing end portions with one of the end portions fixedly attached to its respective lever. Each lever fulcrum section has a lever bearing surface including one of (i) a line-of-contact rounded bearing edge oriented perpendicular to the lever longitudinal axis or (ii) a flat bearing face. The lever bearing surface of each lever touches the middle bearing portion of the flexure plate. Each assembly further includes a sensor having a support surface, a force transmission platform, and an output representative of total force applied to the force transmission platform. At least one force transmission link is adapted to connect each lever connector section to the force transmission platform, and at least one load link is adapted to connect the lever load section of each lever to the weigh frame.
