CircuitPython library for controlling a MAX31855 Thermocouple sensor chip.
Project description
Introduction
CircuitPython driver for the MAX31855 Thermocouple Amplifier Breakout
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.
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-max31855To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-max31855To 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-max31855Usage Example
Of course, you must import the library to use it:
import adafruit_max31855You 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:
print(sensor.temperature)The temperature is read in degrees Celsius (°C). You have to convert it to other units yourself, if you need it.
