:postal_horn: :ocean: Firmware + Python library for working with the FS2012 flow sensors

FS2012 flow sensor

Firmware, Python library, PyQt GUI for working with the FS2012 flow sensors. Supports only Python 3. For a Python 2-compatible version of the software, see the original repo.

Requirements

• pyserial
• pyqt5

Installation

Navigate to the directory that houses setup.py and install in editable mode:

cd fs2012_flow_sensor/software/fs2012_flow_sensor
pip install -e .

DataReader Example

The below code snippet can be found in examples/data_reader_example.py:

import time
from fs2012_flow_sensor import DataReader

port = '/dev/ttyUSB0'
reader = DataReader(port)
reader.start()
for i in range(75):
    print(reader.get_data())
    time.sleep(0.1)
reader.stop()

Running the pyqt GUI

The script runs from anywhere, and outputs flow_data.txt in the current directory, if the "record" box is checked. Run with:

flow_sensor_app

The script can accept an argument that specifies the path to the uC port. This argument is defaulted to /dev/ttyUSB0. If the above command fails, check that /dev/ttyUSB0 is the correct port. If not, specify it like so:

flow_sensor_app /dev/<my_port>

Running the live plot

The script runs from anywhere, and outputs flow_data.csv in the current directory. Run with:

flow_sensor_live_plot

The script can accept an argument that specifies the path to the uC port. This argument is defaulted to /dev/ttyUSB0. If the above command fails, check that /dev/ttyUSB0 is the correct port. If not, specify it like so:

flow_sensor_live_plot /dev/<my_port>
