The ideal position is at **breathing height** (about 1–1.8 m / 3–6 ft above the floor), either mounted on a wall or placed on a shelf or desk. Avoid positioning the device near windows, doors, radiators, air conditioners, or ventilation outlets, as drafts and heat sources can distort measurements. Keep it away from direct sunlight and do not place it in corners, behind curtains, or too close to people’s faces, as this can lead to unrepresentative readings. A stable, shaded location with normal airflow will provide the most reliable results. The Aranet2 should not be placed in direct sunlight or in areas with a risk of splashing the sensor with different liquids, or high-humidity environments (higher than 85%), such as your bathroom. Place the sensor in a safe place where it cannot accidentally be dropped because it isn’t drop-proof. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.aranet.com/aranet2/aranet2-home/usage-and-measurements/where-to-place-the-device-in-a-room.md?ask=&goal= ``` `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.
