adafruit-circuitpython-mcp9600

Introduction

This is a CircuitPython driver for the MCP9600 thermocouple I2C amplifier. In addition to the MCP9600 breakout, you will also need a thermocouple, which can be found in the Adafruit store. The MCP9600 supports several thermocouple types for different temperature ranges. The “K” type is the default, with a range of -200C to +1372C.

Dependencies

This driver depends on:

Adafruit CircuitPython

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-mcp9600

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-mcp9600

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-mcp9600

Usage Example

This is a simple example showing the hot junction temperature (the temperature at the tip of the thermocouple). You may need to adjust the I2C frequency if you receive input/output errors.

import board
import busio
from adafruit_bus_device.i2c_device import I2CDevice
from adafruit_mcp9600 import MCP9600

i2c = busio.I2C(board.SCL, board.SDA,frequency=200000)
try:
    # using default I2C register and "K" thermocouple
    device = MCP9600(i2c)
    print("temperature(C):",device.temperature)
except ValueError:
    print("MCP9600 sensor not detected")

This example displays the ambient/room and hot junction temperatures at 1 second intervals. Turn on the Mu editor’s plotter option to view the temperatures in a real-time graph.

import board
import busio
import time
from adafruit_bus_device.i2c_device import I2CDevice
from adafruit_mcp9600 import MCP9600

i2c = busio.I2C(board.SCL, board.SDA, frequency=200000)

try:
    device = MCP9600(i2c)
    print("version:", device.version)
    while True:
        print((
            device.ambient_temperature,
            device.temperature
        ))
        time.sleep(1)
except ValueError:
    print("MCP9600 sensor not detected")
