Smart Citizen Sensor Type

smartcitizen/sensor

One Smart Citizen sensor type by id: its name, description, unit, a link to the unit definition and datasheet, and the measurement it makes with that measurement's description. Use it to interpret the sensor ids in device records. An unknown id is refused as VALIDATION.
