# How do I place the sensor in the pot?

Proper sensor placement ensures accurate readings and long-term stability. Follow these steps to correctly position your substrate probe in the pot.<br>

{% stepper %}
{% step %}
Prepare the substrate

* Fill your pot with substrate up to the height where the sensor will be placed.
* Gently tamp down the substrate to ensure it’s firm and level. Check that the height remains correct after tamping.
  {% endstep %}

{% step %}
Position the probe

* Place the sensor in the centre of the pot for the most representative readings.
* Ensure the prongs sit flat and level, not angled, for consistent moisture and EC measurements.
  {% endstep %}

{% step %}
Secure the sensor

* Continue backfilling the pot with the substrate, ensuring the sensor stays in position.
* Tamp down the substrate as you go to remove air pockets and ensure good contact with the probe.
  {% endstep %}

{% step %}
Manage the cable

Loop the cable out of the top of the pot, keeping it secure and out of the way.
{% endstep %}
{% endstepper %}

By following these steps, you’ll ensure stable, repeatable data collection, which will help you make more informed watering and feeding decisions.

## 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/substrate-probes/how-do-i-position-my-soil-probe-for-my-pot-size/how-do-i-place-the-sensor-in-the-pot.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.
