kollektoropencollector

kollektoropencollector is an open-source data-collection platform designed to integrate a variety of sensing devices through open-collector interfaces. The project emphasizes interoperability and modularity, enabling researchers, educators, and hobbyists to collect time-series data from diverse sources with minimal hardware requirements.

Its architecture centers on a lightweight daemon that coordinates data collection, a suite of device drivers offering open-collector compatible interfaces, and adapters that export data to databases or messaging systems. The system uses an event-driven model and a compact data format for efficient transmission, with support for MQTT and HTTP-based endpoints.

In hardware terms, open-collector refers to digital lines that can be pulled low by devices and require pull-up resistors. The project provides wiring diagrams, driver logic, and example circuits to support simple multi-device configurations and wired-OR setups.

kollektoropencollector is released under an OSI-approved license and is maintained by a distributed community of contributors. Documentation covers installation, configuration, driver development, and security considerations, with a focus on portability across single-board computers and today's microcontrollers.
