# FH009/FH010 environmental sensors

FH009 Temperature / Humidity / Barometric Pressure & Light Sensor and FH010 Temperature / Humidity sensors look the same.

They are offered with a cable that has RJ12 connector on one side and separate wires on the other side. The cable length shall be adjusted depending on the installation requirements. RJ12 is connected to XBB006 gateway. The wires on the other side are connected to the connector inside the sensor enclosure as shown below.

The corresponding OW (1-Wire), GND and PWR (+5V) pin pairs are connected internally on the board to enable pass-through connection if it is needed to connect another sensor or interface using the same cable as described in [1-Wire interface](/bbo-gateway-installation-manual/bbo-gateways/1-wire-interface.md).

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://help.boomerang3.com/bbo-gateway-installation-manual/bbo-gateways/xbb006-bbo-1-wire-gateway/fh009-fh010-environmental-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.
