CircuitPython library for Thermistor thermal resistor temperature sensor.

Project description

Introduction

Documentation Status Discord Build Status

Thermistors are resistors that predictably change resistance with temperature. This driver uses an analog reading and math to determine the temperature. They are commonly used as a low cost way to measure temperature.

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

The hardest part of using the driver is its initialization. Here is an example for the thermistor on the Circuit Playground and Circuit Playground Express. Its a 10k series resistor, 10k nominal resistance, 25 celsius nominal temperature and 3950 B coefficient.

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-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix adafruit-circuitpython-thermistor --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-theme

Now, once you have the virtual environment activated:

cd docs
sphinx-build -E -W -b html . _build/html

This 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.
