The Sensor (com.prosyst.mbs.services.da.items.Sensor) device item represents a sensor that measures a physical property. All valid values lie within the range. To present the type of the value you should use the generic parameter Q which extends Quantity<Q>.

To specify what the Sensor measures it is necessary to add a specific attribute. The key of this attribute is SensorAttributes.ATTRIBUTE_MEDIUM and the value can be one of the following constants:

• SensorAttributes.MEDIUM_AIR – used to indicate that a property of air is measured.
• SensorAttributes.MEDIUM_WATER – used to indicate that a property of water is measured.
• SensorAttributes.MEDIUM_SOIL – used to indicate that a property of soil is measured.
• SensorAttributes.MEDIUM_BLOOD – used to indicate that a property of the patient blood is measured. For example blood pressure.
• SensorAttributes.MEDIUM_TILT – used to indicate that the value represented by the FunctionalItem is tilt of something (in most cases the device it self) is measured.
• SensorAttributes.MEDIUM_TANK – used to indicate that the value represented by the FunctionalItem is the level to which a tank is filled.
• SensorAttributes.MEDIUM_TIDE – used to indicate that the value represented by the FunctionalItem is the level of the tide.
• SensorAttributes.MEDIUM_ELECTRICITY – used to indicate that the value represented by the FunctionalItem is related to electricity.
• SensorAttributes.MEDIUM_GAS – used to indicate that a property of any gas substance (if there is no already concrete attribute defined like) is measured.
• SensorAttributes.MEDIUM_PROGRESS – used to indicate that the sensor measures progress. Useful for white good appliances to show the program process.
• SensorAttributes.MEDIUM_BONE – used in medical sensors for example bone density.
• SensorAttributes.MEDIUM_EXHAUST – used to indicate that the sensor measures some property of an exhaust. Exhaust can be defined as a waist product of the normal operation of a device.
• SensorAttributes.MEDIUM_FAT – used in medical sensors for example body fat index or total body fat.
• SensorAttributes.MEDIUM_HEART – used in medical sensors for example heart rate.
• SensorAttributes.MEDIUM_MUSCLE – used in medical sensors for example muscle mass.
• SensorAttributes.MEDIUM_OUTSIDE – used to indicate that the sensor measures outside (outside may mean outside of a building or outside of the system).
• SensorAttributes.MEDIUM_INSIDE – used to indicate that the sensor measures inside (inside may mean inside of a building or inside of the system).
• SensorAttributes.MEDIUM_RAIN – used to indicate that the sensor measures some property of the rain. For example the quantity of the fallen rain.
• SensorAttributes.MEDIUM_SMOKE – used to indicate that the sensor measures some property of smoke. For example how much particulate matter does the smoke contain.
• SensorAttributes.MEDIUM_SOUND – used to indicate that the sensor measures some property of sound.
• SensorAttributes.MEDIUM_BATTERY –used to indicate that the sensor measures some property of battery. For example remaining charge, or voltage, or percentage charge left.
