CircuitPython library for SHT31-D temperature and humidity sensor.
Project description
Introduction
CircuitPython module for the SHT31-D temperature and humidity sensor.
Dependencies
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Usage Example
You must import the library to use it:
import adafruit_sht31dThis driver takes an instantiated and active I2C object (from the busio or the bitbangio library) as an argument to its constructor. The way to create an I2C object depends on the board you are using. For boards with labeled SCL and SDA pins, you can:
from busio import I2C
from board import SCL, SDA
i2c = I2C(SCL, SDA)Once you have created the I2C interface object, you can use it to instantiate the sensor object:
sensor = adafruit_sht31d.SHT31D(i2c)And then you can start measuring the temperature and humidity:
print(sensor.temperature)
print(sensor.relative_humidity)Contributing

Building locally
To build this library locally you’ll need to install the circuitpython-build-tools package.
python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-toolsOnce installed, make sure you are in the virtual environment:
source .env/bin/activateThen run the build:
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-sht31d --library_location .Sphinx documentation
Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):
python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-themeNow, once you have the virtual environment activated:
cd docs
sphinx-build -E -W -b html . _build/htmlThis will output the documentation to docs/_build/html. Open the index.html in your browser to view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to locally verify it will pass.
