OpenDarkSky.

Measuring Our Night Sky.

The OpenDarkSky project is building a global network of open-source sensors to scientifically measure light pollution and key environmental data.

A collaboration between:

SC Robotics Libre Space ESA

Open Data for a Healthier Planet

From vanishing stars to disruptions in ecosystems, the effects of light pollution and environmental change are profound. OpenDarkSky provides the tools to fight back: an open, global, and scientifically accurate network to monitor our world, empowering communities with the data to drive change.

Map Light Pollution

Our network's primary mission is to gather high-precision photometric data to create a real-time global map of sky brightness.

Monitor Key Metrics

Each device also records crucial data like temperature and humidity, providing a richer understanding of local environmental conditions.

Democratize Science

All data is open and accessible, empowering citizen scientists, researchers, and policymakers to protect our environment.

Explore the Live Data Map

Our living map is now online. This interactive platform brings the OpenDarkSky network to life, offering real-time insights and historical trends from every deployed sensor across the globe. You can now explore the data, identify light pollution hotspots, and track environmental changes as they happen.

Conceptual design of the autonomous OpenDarkSky environmental sensor station

The OpenDarkSky Sensor

At the heart of the project is a custom-designed, autonomous device. Each station is a self-contained unit engineered for long-term, unattended operation in any environment. It collects data locally and periodically uploads it to the cloud via WiFi or cellular network, ensuring a robust and scalable global network.

  • High-Precision Photometer: Accurately measures sky brightness to quantify light pollution.
  • Multi-Sensor Suite: Integrates sensors for temperature, humidity, and other key environmental parameters.
  • Autonomous & Connected: Features offline data storage and flexible connectivity options (WiFi/Cellular) for "set and forget" deployment.
  • Open Source: Both hardware and software designs are fully open, inviting global collaboration and innovation.
