# Calculating of the dew point temperature

Based on the air temperature and humidity value, it is possible to determine the dew point temperature.

In the example, [Multisensor IR](https://storage.grenton.com/docs/datasheets/Dokumentacja_techniczna_MultiSensorIR_1.1.4-2150.pdf) measurements were used to determine it.

In order to calculate the dew point temperature you have to create:

- user feature of type *number* in the CLU:

![](https://knowledgebase.grenton.com/hubfs/image-png-Sep-12-2023-11-34-42-4471-AM.png)

- the script:

```
temp = CLU->MS_TEMPERATURE_SENSOR_01->Valuehumidity = CLU->MS_HUMIDITY_SENSOR_01->ValueCLU->dew_point_temp=(humidity/100)^0.125*(112+0.9*temp)+0.1*temp-112
```

 

-  interface containing *Value\_V2* widgets displaying the appropriate values:

![](https://knowledgebase.grenton.com/hubfs/image-png-Sep-12-2023-11-36-32-3130-AM.png)

After sending the configuration to the CLU, the interface should display the values of air temperature, humidity and dew point temperature:
