# Exporter for the DHT11 sensor [](https://ci.onders.org/finga/dht11-exporter)
|
||
|
|
A Prometheus exporter for the DHT11 sensor.
|
||
|
|
|
||
|
|
## Build
|
||
|
|
Cargo, the Rust package manager, is used to build this project.
|
||
|
|
|
||
|
|
### Same architecture as system
|
||
|
|
Compile it for the same architecture as the build system:
|
||
|
|
```sh
|
||
|
|
cargo build --release
|
||
|
|
```
|
||
|
|
|
||
|
|
### Cross-compile for amd64 (recent RaspberryPi)
|
||
|
|
Cross-compile it for the amd64 architecture:
|
||
|
|
```sh
|
||
|
|
PKG_CONFIG_SYSROOT_DIR=/usr/aarch64-linux-gnu cargo build --target aarch64-unknown-linux-gnu --release
|
||
|
|
```
|
||
|
|
|
||
|
|
## Debian
|
||
|
|
To build a package for Debian, Raspbian, and so on,
|
||
|
|
[`cargo-deb`](https://crates.io/crates/cargo-deb) can be used.
|
||
|
|
|
||
|
|
The package comes with an automatically started and enabled systemd
|
||
|
|
service unit which can be configured via
|
||
|
|
`/etc/default/dht11-exporter`.
|
||
|
|
|
||
|
|
### Same architecture as system
|
||
|
|
Build a `deb` package for the same architecture as the build system:
|
||
|
|
```sh
|
||
|
|
cargo deb
|
||
|
|
```
|
||
|
|
|
||
|
|
### Cross-compile for amd64 (recent RaspberryPi)
|
||
|
|
Build a `deb` package for the amd64 architecture:
|
||
|
|
```sh
|
||
|
|
PKG_CONFIG_SYSROOT_DIR=/usr/aarch64-linux-gnu cargo deb --target aarch64-unknown-linux-gnu
|
||
|
|
```
