Reading Types is a feature that helps you create/edit/update measurements coming in as a result of sensor’s and actuator’s readings, such as temperature, humidity, location, velocity, acceleration, radiation, and so on.
These include:
- Name
- Data type - defines the type of data coming from the sensor (NUMERIC, STRING or BOOLEAN)
- Default unit - displays after you fill out Measurement Units tab
- Data size - represents volume of data coming from device sensor (e.g. 1)
- Labels - values separated with comma (e.g. data size is 2, longitude, latitude)
- In use - indicates if the reading type is currently in use or not
Search box enables you to search any reading type by its name.
