NOTE: The new Boltwood Cloud Sensor III uses a new generation of sensors, improving upon the prior generation of Boltwood Cloud Sensor II. It also adds new capabilities that were not available on earlier models. Unlike the older models, these units use new software, including the current state-of-the-art ASCOM Alpaca technology for Safety Monitoring and Observing Conditions.

When it detects adverse conditions, the Boltwood Cloud Sensor III will trigger a contact closure (relay) output. When connected to an observatory roof controller such as the MaxDome II system, this will cause the observatory to close. Note that this will not park your telescope or other equipment.

The Sun Shield protects the weather sensors underneath from direct sunlight, while allowing air to flow through freely. Underneath the Sun Shield are power and roof cable connections, plus several additional sensors. Keep this area clear and open to the environment, do not cover it. DIFFRACTION LIMITED...

3 – Equipment Installation The Boltwood Cloud Sensor III must have a clear view of the sky overhead, and unobstructed air flow. It can be installed on a pole, fence post, etc. It is also possible to install it on a roof fascia, although you should avoid installing over a potentially hot surface such as concrete or in any situation that blocks wind flow.
If the AC power supply is not being used, connect the cloud sensor to a 12V power source. Although nominally a 12V input, it will accommodate a voltage range of 10.5V to 24V. The polarity of the connector is not important – it can be connected either way. DIFFRACTION LIMITED...
The contact will also close if power is lost to the cloud sensor, which is useful for shutting down the observatory in the event of a power loss. This assumes your roof system has a battery backup. DIFFRACTION LIMITED...
