# PyCampbellCR1000 — Communication tools for Campbell CR1000-type Dataloggers

License: copyleft · Maintenance: abandoned · Downloads: 94.1K/mo

## What it is and what it does

PyCampbellCR1000 is a Python interface for querying Campbell CR1000-type environmental dataloggers. It abstracts the communication protocol (supporting TCP, UDP, Serial, and GSM connections) and provides methods to read the datalogger's internal clock, list available data tables, retrieve logged measurements within a date range, and download file content. Data is returned as dictionaries or can be exported to CSV.

The package is designed for post-processing workflows where a datalogger is already configured and deployed; it does not modify datalogger settings beyond adjusting the internal clock. It was last released in 2017 and is no longer actively maintained, though the repository remains archived on GitHub with no recent commits.

Use it for:

- Retrieve environmental sensor data (temperature, voltage, current) from a deployed CR1000 datalogger on a scheduled basis for analysis.
- Synchronize a remote datalogger's internal clock with a central time source via Python script.
- Export logged measurements from a specific table and date range to CSV for post-processing or archival.
- List available tables on a datalogger to discover what data streams are being recorded.
- Integrate datalogger queries into an automated data pipeline for environmental monitoring stations.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Communicates with Campbell CR1000-type dataloggers over TCP, UDP, Serial, or GSM connections to query time, retrieve data tables, and download logged measurements.

No, unless you are maintaining legacy code already using this package. The project is abandoned (no releases since 2017, last commit 2023-05-25), and its runtime dependency PyLink is also unmaintained. Compatibility with modern Python versions is uncertain. If you need to communicate with a Campbell datalogger on a current system, evaluate maintained alternatives or contact Campbell for supported libraries.

## Install

pip install pycampbellcr1000
uv add pycampbellcr1000
poetry add pycampbellcr1000

## Installing PyCampbellCR1000

Before you install: High install friction: no runtime dependencies listed, but the package is abandoned (last commit 2023-05-25, no releases since 2017-11-29). Maintenance status is stalled; expect compatibility issues with modern Python versions despite historical claims of 2.6+ and 3.x support.

License in practice: Licensed under GNU GPL v3 (copyleft). Any derivative work or bundled distribution must also be open-source under GPLv3; proprietary or closed-source projects cannot incorporate this code without releasing their own source.

Quickstart:

from pycampbellcr1000 import CR1000
import datetime
device = CR1000.from_url('tcp:host-ip:port')
device.gettime()
data = device.get_data('Table1', datetime.datetime(2012, 7, 16, 11, 0, 0), datetime.datetime(2012, 7, 16, 12, 0, 0))

Requires a Campbell CR1000, CR800, or compatible datalogger accessible over TCP, UDP, Serial, or GSM; PyLink library dependency must be available.

Verify before relying:

- Whether PyLink dependency is still maintained and compatible with modern Python versions.
- Actual compatibility with Python 3.x versions beyond 3.4, given the package's abandonment.
- Whether the package works reliably with CR3000 dataloggers as claimed.
