ArduinoThermoControlWeb

A flask server that should simplify the logging of our temp control. The website assumes that the Arduino is connected via a serial device. For the moment we have to following abilities:

• It shows data in a long list for the moment.
• It is possible to save the values to an hdf5 file.
• The setpoint can be changed in the config page.

On the technical side we use the following ingredients:

• Communication with the Arduino is done through the Serial interface.
• Updates are done through flask_socketio
• The layout is made nice through flask_bootstrap.

The project should serve as a boilerplate for our other sensors too.

Installation

• create a new directory
• clone the repository through 'git clone ...' in the new folder
• create a new virtualenv through 'conda create -n YOURNAME python=3.6'
• activate the virtualenv through 'source activate YOURNAME'
• install the dependencies through 'pip install -r requirements.txt'
• start it through 'start.sh'
• open it in a brower on 'localhost:5000'

Usage

The server itself

• activate the virtualenv through 'source activate YOURNAME'
• start it through 'start.sh'
• runs on 'localhost:5000'

Test without Arduino

If you want to test the serial port without having an Arduino, you should just start another terminal, and run the simSerialPort.py file through 'python simSerialPort.py'

Saving to hdf5

We can save the last data to an hdf5 file by calling the 'file/FNAME.h5'. It is assumed that the file is already created. Most likely from some program from the labscriptsuite or our NaLi control system. An example for calling it from matlab is found in matlabPythonComm.m .

TODO

1. Plots and nicer table ?
2. Error logger to communicate with slack or via email.
3. Allow for changing the parameters of the feedback loop through some serial communication.
