Digital Multimeter #
Digital Multimeter provides both a command-line interface and a Python module interface to receive data from a variety of digital multimeters. Checkout the list of supported multimeters.
Features #
- Command line and Python module interface to digital multimeters
- Continuous live data readings (using
--count 0
) - Output in json or csv formats
- Output to console or file, allowing other tools to pickup and use the data
- Configuration via config-file or environment-variables
- Easy to expand for new digital-multimeter protocols
- Easy installation using PyPI
pip
- Plenty of documentation and examples - https://digital-multimeter.readthedocs.io
Installation #
user@computer:~$ pip3 install digital-multimeter
Command Line Usage #
Continuously read the digital-multimeter and pipe the JSON output through jq
making it look prettier.
user@computer:~$ dmm read --connect /dev/ttyUSB0 --count 0 | jq .
