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 "Cloud" graphic .
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.
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.
To distinguish between day and night. It will even detect the Moon.
