Conclusions

We have constructed cloud monitors based on simple infra red detectors which are sensitive to all visual clouds in their field of view. With compensation for temperature variations in the canister of the infra red element, it is possible to produce an output which can veto cloudy periods with a simple voltage level veto. The cloud detector has no moving components and draws little current. It is thus suitable for remote long term cloud monitoring.
