# Calibration of the temperature measured by the temperature sensor

If external elements have a negative impact on the correctness of the temperature measurement it may be necessary to calibrate the measured temperature.

To perform temperature calibration, proceed as follows:

 \* create two features in CLU user features:  
![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Nov-13-2024-02-04-18-5873-PM.png?width=688&height=529&name=image-png-Nov-13-2024-02-04-18-5873-PM.png)

where:  
***calibration*** - the value by which the measured temperature will be calibrated,  
***calib\_temp*** - temperature value after calibration in Celsius degree

\* create a script:  
![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Nov-13-2024-02-06-04-8054-PM.png?width=481&height=104&name=image-png-Nov-13-2024-02-06-04-8054-PM.png)

`CLU->calib_temp = CLU->ONEW_SENSOR1->Value - CLU->calibration`

\* assign the script to the ***OnValueChange*** event in the temperature sensor:  
![](https://knowledgebase.grenton.com/hs-fs/hubfs/image-png-Nov-13-2024-02-11-53-5433-PM.png?width=836&height=643&name=image-png-Nov-13-2024-02-11-53-5433-PM.png)

The configuration created in this way should be sent to the CLU unit.

**Note!** The ***Calibration*** feature is available in the PANELSENSTEMP object of the Smart Panel module from FW 6.01.08, which allows automatic temperature calibration with a constant value in the range -10 to +10 °C.
