CircuitPython library to support Honeywell MPRLS digital pressure sensors.

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_
• Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-mprls/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-mprls

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

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-mprls

To install in a virtual environment in your current project:

.. code-block:: shell

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

Usage Example

.. code-block:: python3

import time
import board
import adafruit_mprls

i2c = board.I2C()

# Simplest use, connect to default over I2C
mpr = adafruit_mprls.MPRLS(i2c, psi_min=0, psi_max=25)

while True:
    print((mpr.pressure,))
    time.sleep(1)
