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.
Installing from PyPI¶
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-max31855
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-max31855
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-max31855
Of course, you must import the library to use it:
You also need to create an SPI interface object, and a pin object for the chip select pin. You can use any pin for the CS, but we use D5 here:
from busio import SPI from digitalio import DigitalInOut import board spi = SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI) cs = DigitalInOut(board.D5)
Next, just create the sensor object:
sensor = adafruit_max31855.MAX31855(spi, cs)
And you can start making measurements:
The temperature is read in degrees Celsius (°C). You have to convert it to other units yourself, if you need it.
