RPI SHT31

A golang program to read humidity/temperature from a SHT31 sensor (https://wiki.seeedstudio.com/Grove-TempAndHumi_Sensor-SHT31/) using periph.io (https://periph.io/) which exports data to an influxdb instance.

Requirements

1. You'll need a raspberry pi 3 with I2C. The pi must be reachable over SSH.
2. Copy the .env.dist to .env and fill the mandatory values.

Commands

Build (ARM)

make build

The influxdb credentials are injected at build time through ldflags.

Deploy

make deploy

Once deployed, you may want to run the command as a service. Just create a new systemd unit from the systemd/sensor.service on the pi.

Improvements

• I'd like to refactor the sht31 module to be fully compatible with periph.io.
• generate a custom linux kernel with buildroot/yocto to be able to minimize the footprint ?
