Connect the sensor to an I2C bus on your board

Board            SHT31
VCC  <-------->  VCC
SCL  <-------->  SCL
SDA  <-------->  SDA
GND  <-------->  GND

Make sure the power supply and logic levels match between the board and the sensor.

Copy this repository to the board and launch the services

For armhf:

docker-compose build --pull
docker-compose up

For arm64: First make the changes described in following files for arm64:

docker-compose.yml
flaskapp/Dockerfile
sht31-influxdb/Dockerfile
kiosk/Dockerfile

and do

docker-compose build --pull --build-arg IMAGE_ARCH=linux/arm64
docker-compose up

Docker compose will start a browser in kiosk mode and point it to the web page served by the flaskapp. The page contains two tabs; one for realtime chart and other for historical data chart.

This was tested on Apalis iMX6 Evaluation Board, using Apalis I2C1 (/dev/apalis-i2c1). Adjust docker-compose.yml to use the I2C bus for a particular module/familiy.
