There is a core description about the idea, the data flow, the need for the partner stations including some cost estimations. This is the content of EarthLAT1200_Project.pdf:

  • aim of the project
  • core meeting point
  • data flow structure
  • short outlook of a single partner station
  • different contribution levels for partner sations
  • estimated costs of a partner station.

A more detailed description of a partner station - here KEPLERUHR - contains:

  • outlook of a single partner station
  • HW/SW-structure
  • configuration files for automated readout
  • estimated costs of a partner station.

Different approaches to the design of the camera and housing exist. Within our experience there are some points of common interest:

  • keep the housing waterproof from top, but allow for a hole downside for letting humidity flow outside
  • protect the housing from direct sun radiation by a separated shield of e.g. aluminium - which also keeps hard rain/snow from falling to the housing/the lens
  • the housing should allow for WLAN signal passing into it if connected wireless
  • at Sdcam-Raspi there are two external temperature sensors: one for inside the housing and the second for outside the housing; prevent them from direct sun radiation
  • the Sdcam-Raspi must be plugged via a electromechanical switch to power in order to power on before sunrise and power off ca. 30 min after sunset; The Raspi goes to HALT/OFF modus ones a day and therefore does not need to operate permanently.

Here are some images of cameras, camera housing, alu shields, power support

Most Resources are within the GitHub repository kepleruhr/Sdcam. There are step by step introductions within two branches/approaches to get the Raspberry system running:

  1. image - download a complete OS-image, burn a SD-card, steps for operation, preconditions
  2. source - prepare a running Raspi-OS, apply a ram disk, add modules for camera, temperature sensor, create a, sundialcam Python scripts, etc.

Due to their size the OS image files are at another place ( server):
