# How does the dew point limit work?

Instead of requiring complex calculations, you just set how close to the dew point you want to be alerted.

### How it works:

* The sensor automatically calculates the dew point based on temperature and humidity.
* You set a limit to determine when you’ll receive an alert.
* For example, if you set the limit to 1°C, you’ll be notified when the ambient temperature is 1°C away from the dew point - helping you prevent condensation and mould risks before they become a problem.

### Dew point graph

The dew point graph visually displays:

* How close you are to the dew point in real time.
* The limit you’ve set, so you can track trends and make adjustments as needed.<br>

With the Grow Sensor, no dew point calculations are needed - just set your limit and let the sensor do the work.
