am2320_exporter

Prometheus Exporter that acquires temperature and humidity from the sensor AM2320.

Description

This Exporter is created on the assumption that it will run on a Raspberry Pi.
For temperature and humidity monitoring using Raspberry Pi and Docker.
It is also possible to deploy on Kubernetes.

Exported metrics

metric	description	labels
am2320_temperature_gauge	temperature obtained from am2320
am2320_humidity_gauge	humidity obtained from am2320

Requirements

• Go 1.12.x ~ (Your computer or Raspberry Pi)
• Docker (Raspberry Pi)

Usage

The connection between the Raspberry Pi and the AM2320 sensor has been completed in advance.

Go

Build the program on your computer or Raspberry Pi.
export GO111MODULE=on
GOOS=linux GOARCH=arm GOARM=7 go build

Binary execution.
sudo ./am2320-exporter

Docker

docker run -i -t -d --name am2320_exporter -p 9430:9430 --privileged yudaishimanaka/am2320-exporter-armv7l

Kubernetes

Configure Pod Affinity according to your Kubernetes cluster and deploy appropriately.
