A Python based data logger

Project description


General purpose data aquistion, processing, and logging platform written in Python. DataBear is hardware independent, but is meant to be easily integrated via a custom hardware interface provided by the user.


  • Easy to use - intuitive setup and configuration.
  • Versatile - use on any hardware device that runs Python.
  • Extendible - add new methods for measurement as needed.

Some potential usage scenarios:

Here are some random ideas to give a sense for DataBear capabilities (some capabilities under development).

  • Run DataBear on a Raspberry Pi ( to read a Modbus temperature sensor. The sensor could be connected to a USB port on the Pi via an RS485 to USB converter and data could be read every second, averaged, and stored to CSV.
  • Integrate DataBear into an existing Linux based measurement platform, such as the Dyacon MDL-700 ( In this case, DataBear is utilized by pyMDL ( to schedule measurement and storage, while pyMDL specifies hardware configuration.

Ideal Datalogger Features vs Data Bear 0.2
