# Sensors

### Sensors Tab

The sensors tab is used to record information about the sensors taking measurements and their calibrations.<br>

**Sensors**

* Each row in the **Sensors** table represents a sensor such as an anemometer, wind vane, pyranometer etc.
* Sensor details are prepopulated with any available details extracted from the raw logger file ingestion to BrightHub.
* You can edit details of the Sensor OEM, Sensor Model and Sensor Type - common sensor OEMs and Models are available to select from the drop down menu in each of these fields.
* You can also specify the sensor Serial Number, whether the sensor Is Heated, the Instrument Point of Interest Height and Sensor Body Size.
* To add calibration details::

1. Select the + icon to add calibration details.<br>

2. Select the Measurement Type to which the calibration details apply.\
   \
   For sensors which take multiple different measurements, such as sonic anemometers, you should add calibration details for each measurement type separately in consultation with calibration certificates.

3. Specify any available details about the calibration:
   * For wind speed measurements, specify the Calibration Slope and Calibration Offset.
   * For solar measurements, specify the Calibration Sensitivity.
   * Include details of the Calibration Organisation, Place of Calibration, Date of Calibration, Calibration ID, Calibration Revision and Uncertainty K Factor.
   * Provide the Report File Name and Report Link for the calibration certificate.

* To view existing calibration details, click the down error on the left hand side next for your chosen sensor.<br>

* To add a new sensor, click 'Add Sensor'. You must map the new sensor to a measurement before BrightHub will allow the change to be saved.<br>

**Sensor Mapping**

* Each sensor must be mapped to at least one corresponding measurement point.
* This is so that the calibration details can be compared with the information programmed in the logger - for example to compare the logger slope and offset with the calibration slope and offset.
* To **Map Measurements to Sensors**:

1. Click on the Measurement you wish to map, for example 'Spd1\_80m' (Note that ticks appear next to measurements and sensors which are already mapped)&#x20;

   <figure><img src="/files/jBgZ0RZfX4ZXbP2qJE2d" alt=""><figcaption></figcaption></figure>
2. Select the corresponding sensor from the list of Sensors, for example Thies First Class Advanced, serial number 2.
3. Click on Map Sensor.\
   A new row will appear in the **Mapped Sensors** table containing the Measurement Point, Sensor it is mapped to, Date From and Date To.
4. You can freely edit the dates of a sensor mapping provided there is no overlap in sensor mappings for a single Measurement point.

* You can map a measurement point to two distinct sensors provided the dates do not overlap, for example in the case of a sensor replacement:\
  \
  In this example the 'Spd1\_80m' measurement point is mapped to sensor 1 from the start of the measurement campaign.\
  On 2016-04-01 the sensor was replaced so the same measurement point 'Spd1\_80m' is mapped to sensor 2.\
  Note that the time periods for the two sensor mappings do not overlap.

  <figure><img src="/files/6tUiewtFW2pSUcGZupG1" alt=""><figcaption></figcaption></figure>
* You can map several measurement points to the same sensor, for example in the case of a sonic anemometer or thermohygrometer, for which several measurements are taken by a single sensor.
* The Sensors table and sensor mappings may be prepopulated with sensors.\
  This varies for different logger types as there are different levels of detail in the metadata for different logger types.\
  The Sensors tab lists sensors BrightHub has identified from the ingested files but you should add sensor details and update sensor calibration details and mappings in conjunction with installation and maintenance documentation.
