Abstract
There is disclosed a wireless silage 104 sensor unit 102 with one or more sensors 402, 404, 406, 408 for sensing physical and/or chemical characteristics of the silage, and a transmitter 410 coupled to the one or more sensors for wirelessly transmitting the characteristics. A size and/or a shape of the sensor unit 102 is adapted for sensor unit 102 to be embedded in the silage 104 during storage of the silage and for the silage 104 to be provided with the sensor unit 102 during storage of the silage and for the sensor unit to endure a decompacting process of the silage during which the silage is decompacted and possibly mixed with further ingredients and where the sensor unit 102 is furthermore adapted to be sorted out unbroken after the decompacting process.
Claims14
A wireless silage (104) sensor unit (102) comprising
- one or more sensors (402, 404, 406, 408) for sensing physical and/or chemical characteristics of the silage, and
- a transmitter (410) coupled to the one or more sensors for wirelessly transmitting the physical and/or the chemical characteristics, and
- wherein a size and/or a shape of the sensor unit (102) is adapted for the sensor unit (102) to be embedded in the silage (104) during storage of the silage and for the sensor unit (102) to endure a decompacting process of the silage during which the silage is decompacted and possibly mixed with further ingredients and
- wherein the sensor unit is furthermore adapted to be sorted out unbroken after the decompacting process.
A wireless silage sensor unit according to claim any of the preceding claims, wherein the size and/or shape of the sensor unit (102) is adapted so that the animals (602) can sort out the sensor unit (102) when the silage (104) with any further ingredients is used as fodder.
A wireless silage sensor unit according to any of the preceding claims, wherein the shape of the sensor is substantially a sphere, in order to provide a sensor unit to be embedded in the silage (104) during storage of the silage and to endure the decompacting process of the silage and in order to provide a sensor unit which can be sorted out unbroken after the decompacting process.
A wireless silage sensor unit according to any of the preceding claims, wherein the size and/or the form of the sensor unit (102) is adapted so that the volume of the sensor unit (102) is larger than 0.000004 m3.
A wireless silage sensor unit according to any of the preceding claims, wherein the form of the sensor unit (102) is substantially a sphere.
A wireless silage sensor unit according to any of the preceding claims, wherein substantially no free space is provided within the sensor unit (102) and/or any components (402, 404, 406, 408, 410, 411) within the sensor unit are embedded in one or more materials (414) forming the sensor unit (102) and/or any opening in the sensor unit (102) is provided with a size only for enabling sensing the physical and/or chemical characteristics of the silage (104).
Method of wirelessly sensing physical and/or chemical characteristics of silage with a wireless silage sensor unit (102) in order to determine a quality of the silage (104), the method comprising
- providing (702) the silage (104) with one or more sensor units (102), and
- sensing one or more physical and/or the chemical characteristics of the silage (104) with the sensor unit (102) during a conservation period of the silage (104), and
- wirelessly transmitting the one or more physical and/or the chemical characteristics of the silage (104) in order to determine the quality of the silage (104), and
- decompacting (704) and possibly mixing (704) the silage (104) and the one or more sensor units (102) with further ingredients in a decompacting process, and
- sorting out (706) the one or more sensor units (102) unbroken after the decompacting process.
