# Capteur PIR

TX LIGHT PIR T\&H : calibration CO2

La détection d’une **présence** par le capteur **PIR** déclenche **l’envoi immédiat d’une trame de données**.\
Si le capteur ne détecte plus de mouvement, un délai de **2 minutes** est appliqué afin de **confirmer l’absence** avant l’envoi de la trame correspondante.

La **sensibilité par défaut** du capteur est réglée sur **sensibilité élevée**. Si la détection vous semble trop sensible pour votre application, vous pouvez la passer en **sensibilité moyenne** ou **basse**.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/capteurs/editor-5/utilisation/capteur-pir.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
