Temperature SNSPDs influx

This script is used to monitor the temperature of a SNSPDs system (IDQ 281 SNSPD system in this case), running with the SRS CTC100 Temperature controller. In particular, the scripts periodically retrieves the temperature value from the CTC (using USB or Ethernet interface) and write the values to an Influx time series database.

Outside of this script, the data is visualized using Grafana.

Installing the package

The software can be installed from Pypi using the following command:

pip install temperature-snspds-influx

or

python -m pip install temperature-snspds-influx

You can check that the package has been succesfully installed by executing the command:

temperature-snspds-influx --version

or

python -m temperature_snspds_influx --version

The command help can be retrieved with -h or --help.

Configuration

The example configuration file can be copied to the current directory in the config.toml file by simply running the temperature-snspds-influx script (with no file located at the target file). The target file can be changed with the -f or --file command line parameter.

All the parameters of the configuration file must be set.

The example configuration file is displayed below and can be found here:

# Configuration file for temperature-snspds-influx.

[influx]

# Endpoint of the influx database.
endpoint = ""

# Token to use for influxdb.
token = ""

# Name of the database to write to.
db = ""

[ctc]

# Method to connect to the CTC. It should be either "usb" or "ethernet".
method = ""

# Address of the CTC. It should be a COM port or tty for USB
# and ip_address:port for ethernet.
address = ""

# Name of the instrument that recovers the data.
instrument = ""

# Number of digits requested to the CTC (1, 2, 3, 4, 5 or 6).
precision = 6

Running the script

The script can be executed with the following command:

temperature-snspds-influx -f config.toml -l temperature-snspds-influx.log -vvv

where the -f config.toml is to make it explicit in this example, the -l temperature-snspds-influx.log to set a log file and -vvv to specify a log level.
