# What soil probes are compatible with the Grow Sensor?
The Grow Sensor is designed to work with a wide range of substrate sensors, ensuring an open and flexible ecosystem.
Unlike many closed-system products, we believe in giving growers the freedom to choose the best tools for their needs.
To use a substrate sensor, you’ll need to purchase our affordable soil probe adaptor cable. Once connected, you can integrate any of the following probes with your Grow Sensor:

## 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://faq.growsensor.co/substrate-probes/what-soil-probes-are-compatible-with-the-grow-sensor.md?ask=&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.
