Humidity This IPSO object should be used with a humidity sensor to report a humidity measurement. It also provides resources for minimum/maximum measured values and the minimum/maximum range that can be measured by the humidity sensor. An example measurement unit is relative humidity as a percentage. 3304 urn:oma:lwm2m:ext:3304:1.1 1.0 1.1 Multiple Optional Sensor Value R Single Mandatory Float Last or Current Measured Value from the Sensor. Min Measured Value R Single Optional Float The minimum value measured by the sensor since power ON or reset. Max Measured Value R Single Optional Float The maximum value measured by the sensor since power ON or reset. Min Range Value R Single Optional Float The minimum value that can be measured by the sensor. Max Range Value R Single Optional Float The maximum value that can be measured by the sensor. Sensor Units R Single Optional String Measurement Units Definition. Reset Min and Max Measured Values E Single Optional Reset the Min and Max Measured Values to Current Value. Application Type RW Single Optional String The application type of the sensor or actuator as a string depending on the use case. Timestamp R Single Optional Time The timestamp of when the measurement was performed. Fractional Timestamp R Single Optional Float 0..1 s Fractional part of the timestamp when sub-second precision is used (e.g., 0.23 for 230 ms). Measurement Quality Indicator R Single Optional Integer 0..23 Measurement quality indicator reported by a smart sensor. 0: UNCHECKED No quality checks were done because they do not exist or can not be applied. 1: REJECTED WITH CERTAINTY The measured value is invalid. 2: REJECTED WITH PROBABILITY The measured value is likely invalid. 3: ACCEPTED BUT SUSPICIOUS The measured value is likely OK. 4: ACCEPTED The measured value is OK. 5-15: Reserved for future extensions. 16-23: Vendor specific measurement quality. Measurement Quality Level R Single Optional Integer 0..100 Measurement quality level reported by a smart sensor. Quality level 100 means that the measurement has fully passed quality check algorithms. Smaller quality levels mean that quality has decreased and the measurement has only partially passed quality check algorithms. The smaller the quality level, the more caution should be used by the application when using the measurement. When the quality level is 0 it means that the measurement should certainly be rejected.
