# Mount Wildfire Sensors

## Mount using treenails (long term)

Treenails are wooden pegs used to securely mount sensors to a tree. As they are made from wood, they do not affect the health of the tree. Over time the tree's moisture causes the treenails to expand which securely attaches the sensor to the tree.

Drill a 10 mm hole into the tree 3 m from the forest floor on the side of the tree where sunlight would strike the tree at 12:00 noon. The treenails are fed through a loop in the sensor and a spacer and then hammered into the tree.

1. With the help of an assistant, stabilize the ladder against the tree.
2. Locate the correct height (3 m) and direction (facing sun at 12:00 noon).
3. Carefully remove a small portion of the bark with an axe at that location. **Try not to excessively damage the tree.**

4. Carefully drill a hole approximately 6-7 cm into the tree using the 10mm drill bit. **Do not drill deeper than this recommended depth to prevent unnecessary damage to the tree.**

When drilling into a hardwood tree, start with a smaller drill bit to drill a pilot hole then drill with the 10mm drill bit to complete the drill hole. **Ensure you are using a drill bit for wood**.

5. Insert a treenail through the sensor's loop, slip a **spacer** onto the treenail and then **carefully** hammer the treenail into the hole. **Ensure the treenail is not damaged by the hammering.**

6. Ensure the sensor is securely deployed to the tree and hanging loosely and vertically.

## Mount sensors using garden wire (temporary only)

Sensors can be mounted using garden wire for short term installations. Garden wire is typically used in agricultural and garden settings such as greenhouses. This solution should only be used for a limited time as the wire will eventually interfere with growth in the tree's girth.

1. With the help of an assistant, stabilize the ladder against the tree.
2. Locate the correct height (3 m) and direction (facing sun at 12:00 noon).
3. Cut a length of garden wire twice as long than the circumference of the tree.
4. Insert garden wire through the spacer and sensor as shown below.

5. Tighten the garden wire around the tree. Ensure it is securely attached and that the sensor cannot slip or move.

## Next steps

Allow the Wildfire Sensor to calibrate for 14 days.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.dryad.app/dryad-documentation/silvanet-deployment/deploy-sensors/mount-wildfire-sensors.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.
