The AAG CloudWatcher cloud detector is a high accuracy, low-cost Cloud Sensor.

Advantages:

• Full information about sky conditions
• Very affordable price
• Reliable readings
• Easy interpretation of all information
• Connectable to the SOLO for low power, 24×7 availability
• Software available for:
  • Windows (free)
  • INDILib (free) http://indilib.org/devices/weather-stations/aag-cloud-watcher.html,
  • INDIGO
  • MAC OSX (developed by Richard Francis, GerSpatial, available from the AppStore at a very reasonable cost).
  • And autonomously with the SOLO
  • ASCOM safety monitor and observing conditions drivers available
• Very low maintenance
• New version adapted to work with the Hydreon RG-9 Rain sensor.
• Extremely reasonable cost of eventual servicing/repairs (*)
• Product in constant review and improvement
• With the experience and service of Lunatico Astronomía

The AAG CloudWatcher box. All the data collected by the AAG sensors and the anemometer are reflected in the computer through their corresponding graphics. These allow a comprehensive and easily understandable measurement of atmospheric conditions:

**Please Note when ordering the Cloudwatcher Hydreon version it is also necessary to order the Hydreon Sensor** 

Cloud Sensor

Through an infrared sensor of the AAG CloudWatcher measures the temperature of the sky, and an electronic thermometer measures the internal temperature. Both data are then related by a powerful formula used to determine the existence of clouds. The measuring result is easily read on the graphic “Cloud”.

Unlike other detectors, the AAG CloudWatcher allows the user to set the parameters for measurement, and thus adjust the detection of clouds for each place.

Rain Sensor

CloudWatcher uses a variable capacitor to determine the existence of rain. In addition, the capacitor incorporates an internal resistance for heating the element, drying it, which allows a constant reliable reading.

Light Sensor

To distinguish between day and night. It can even detect the Moon.AAG Cloudwatcher.

Temperature Sensor

Responsible for measuring the ambient temperature.

Relativity humidity sensor (RH & AP version)

The data from this sensor are supported by the SOLO CW (attached image).

Windows program displays the value in the screen, with the dew point, and the data are included in the “Single line data” file (*).

Anemometer (OPTIONAL)

Shows the wind speed.

The AAG cable connects the CloudWatcher instrument to a PC and it is available in 4 lengths: 3, 5, 7, or 10m. (From 2018/November you also can get the AAG CloudWatcher without cable).

It has a special weather-proof connector, IP68, which allows the easy and comfortable installation of the unit. The cable can be routed conveniently through a conduit, the thicker part of it is only 19mm in diameter.

Relay (1) for observatory opening/closing, can withstand a voltage of 220 V. But not being a security cable it is advised to connect it to low voltage devices (12 or 24V).

Technical specifications:

• Power 12 or 15V, current < 1 A
• RS232 Serial port (**)
• Size: 110*85*37 mm.

(**) USB to RS232 adapter available here.

In addition, the AAG CloudWatcher software incorporates advanced features such as:

• Multiple users in LAN (MASTER mode and REMOTE mode operation);
• MASTER and REMOTE installations can be independently parameterized;
• Sky temperature correction model to account for excessive atmospheric longwave radiation during summer;
• All alerts can be defined as sound alerts, with a specific sound file to be played when the alert condition occurs;
• Switch control can be disabled and be performed by an external program (suitable to control other equipment);
• Allows the electrical constants to be changed by the user;
• A complete set of properties/methods for inter-program communications;
• Compatible with existing firmware versions 1.xx, 2.xx and future version 3.xx;
• ACP, Sequence Generator+, CCDCommander, CCDAutopilot, Prism, CCDAutoPilot, and Maxpilote compatible; plus any ASCOM-compliant software.
• With the program, AAG WeatherCentre (***) can combine information from any standard weather station supported by Virtual Weather Station, Weather Display, or Cumulus software.
• Several free programs for mobile devices, for example, the one developed by Francisco Jesús Cortés to allow you to receive an alarm on your mobile phone.

(***) The program AAG WeatherCentre is no longer needed since 2017 because the AAGCloudWatcher measures wind speed and relative humidity. It is fully operational but not being updated – offered “as is”.
