Passive Cloud Cover Detector
Accurate All-Sky Cloud Monitoring
The Passive Cloud Cover Detector (PCCD) uses a hemispherical imaging sensor and advanced image processing algorithms to measure total cloud cover in oktas (0–8).
The sensor captures high-quality sky images and calculates cloud cover with exceptional accuracy and consistency.
The PCCD provides continuous cloud cover measurements from 0 to 100% CCF, making it suitable for reliable monitoring of sky conditions and cloud cover variations.
Installation Plate / Clamp
The installation plate / clamp is available as an additional mounting accessory for the PCCD unit. It provides a convenient solution for secure and stable installation of the sensor.
