Today, the Raspberry Pi NoIR camera module arrived. There is a IR filter in the package so that you can also use this device as normal camera:

Especially plants look totally different without the IR filter, thus the NoIR camera is not only an improvement during night hours.

Hope to get it run (with a servo adding or removing the IR filter) for the next test run of R5 on July 17th:
