"AAG CloudWatcher", a high precision, low cost system for monitoring the sky condition. This has been achieved by, firstly, a clever product design by its creator Antonio Peres, and secondly, by the meticulous production from Lunático Astronomy.

But the AAG CloudWatcher does not stress only its low cost, but also by its high quality and unique features.

Its intuitive graphic software allows an inmediate and very visual reading of information. It lets the user set the measuring parameters, achieving a powerful and very accurate cloud detection. All alerts (cloudy, rain, etc) can be programmed to play sound files; that way, and using a couple of simple and inexpensive "walkie talkies" with "vox" function, the alarm can be heard away from the observatory, eliminating the need for a second computer. There're even several free programs for mobile devices, for exemple:

The AAG CloudWatcher comprises:

  • A box with a special exterior finish that includes 4 sensors that are shown in the program through their corresponding graphs. They allow a thorough and easily understandable measurement of atmospheric conditions:
    1. Clouds 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 graffic "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.

    2. 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.

    3. Light sensor. To distinguish between day and night. It can even detect the Moon.

    4. Temperature sensor.

    5. Anemometer (optional accessory).

  • 3, 5 or 10m. long weather-proof cable with IP68 connector, used to connect the cloudwatcher instrument to a PC.



    AAG CloudWatcher with separate cable
    and IP68 connectors for both the main unit
    and the anemometer.



    The IP68 Weipu connectors allow an installation of the unit so much easier.

    The cable can be routed conveniently through a conduit, the smaller side of
    a cylindrical connector only 19mm. in diameter.



  • Relay (1) for observatory opening/closing.

    (1) The Relay cable can withstand a voltage of 220 vol. 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.

(**) Avaliable USB to RS232 adapter 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 long wave 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, CCDCommander, CCDAutopilot 3, CCDAutoPilot and Maxpilote compatible;
  • Can combine information from any standard weather station supported by Virtual Weather Station or Weather Display software.
