# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://faq.growsensor.co/the-grow-app/how-do-i-set-limits-and-alerts-for-graphs/how-does-the-dew-point-limit-work.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
