CSI-20S Infrared Cloud Sensor
CSI‑20S is a compact, infrared‑based sky monitoring instrument designed for continuous 24/7 operation. It features a 90° field of view and directly outputs total cloud cover as textual data, without generating images. By focusing on cloud‑cover metrics rather than imaging, CSI‑20S streamlines data handling and integration in large networks. Its low power consumption and small footprint reduce site constraints and simplify deployment in remote locations or distributed observation arrays.
Lightweight and straightforward to install, the CSI‑20S supports scalable, flexible rollouts in sparsely serviced areas. The infrared sensing approach helps to maintain continuity when visible‑light methods are limited. Typical use cases include photovoltaic forecasting and performance analysis, solar resource assessment, meteorology, and atmospheric monitoring.
