CC-C05 Series Cloud Cover Monitor (Local Edition)
Product presentation
The Cloud Cover Monitor is a professional meteorological observation device specifically designed for precise measurement of cloud cover and solar transmittance. Utilizing advanced large-scale modeling algorithms combined with professional optical sensing technology, it calculates and analyzes cloud layer transmittance of sunlight in real time, providing users with high-precision cloud monitoring data. This device is suitable for applications in meteorological observation, environmental monitoring, climate research, weather forecasting, agricultural monitoring, and solar power generation. It helps users across various sectors better understand and predict weather patterns and their impacts on solar energy utilization.
Working Principle: Upon power-on, the system initiates initialization. After completion, it transmits designated messages. The system automatically performs image acquisition and analysis every minute, storing real-time results in cache while saving historical data at preset intervals. Clients can access real-time data and configure parameters via RS485 or cloud-based monitoring software.
Product Features
·Continuous observation of cloud cover in the whole sky is automatically carried out, and the 4K resolution is higher, so the calculation result of cloud cover is more accurate.
·The fully automatic deep learning technology quickly identifies and removes non-sky images and automatically optimizes features according to the situation on the scene.
·The professional optical bright light suppression system is not afraid of direct sunlight and can eliminate the capture of solar glare on cloud images.
·The self-developed pixel-level image algorithm can accurately analyze the image, and the data is more accurate and reliable.
·Professional ultraviolet protection coating technology, greatly provide optical device service life.
·Windows and device self-heating features are suitable for various application scenarios.
·Large model algorithm drive: Using advanced machine learning techniques and big data analysis, it can accurately calculate the amount of clouds in the sky and the proportion of sunlight passing through the clouds, providing more accurate data than traditional methods.
·Real-time data analysis and feedback: The device can analyze data in real time and quickly feed back the measurement results of cloud cover and solar transmittance to the user, supporting instant decision-making and analysis.
·Ease of use and interactivity: Equipped with an intuitive user interface, users can easily set up, monitor and interpret data. The software also includes data visualization tools to help users intuitively understand changes in cloud cover and light transmittance.
·Wide range of applications: it is not only suitable for professional meteorological and climate research, but also for agricultural production monitoring, solar power generation efficiency evaluation and other fields, to meet a wide range of application needs.

功能码 Function code | 1 | 0x10：写寄存器功能码 Write register function code |
寄存器起始地址高字节 High byte of the register start address | 1 | 0x01 |
寄存器起始地址低字节 Low byte of the register start address | 1 | 0x08 |
寄存器长度高字节 Register length high byte | 1 | 0x00 |
寄存器长度低字节 Register length in bytes | 1 | 0x03 |
写入数据字节长度 Write data byte length | 1 | 0x06 |
写入第1个寄存器数据 Write the first register data | 1 | 0xXX：寄存器高字节，年：例如2025年则该字节为0x25 The high byte of the register (year): for example, 2025 would be 0x25 |
1 | 0xXX：寄存器低字节，月：例如9月则该字节为0x09 The low byte of the register, month: for example, September is 0x09 | |
写入第2个寄存器数据 Write the second register data | 1 | 0xXX：寄存器高字节，日：例如2日则该字节为0x02 The high byte of the register: for example, 2 means the byte is 0x02 |
1 | 0xXX：寄存器低字节，时：例如8时则该字节为0x08 The lower byte of the register. For example, if the time is 8, this byte is 0x08. | |
写入第3个寄存器数据 Write data to the third register | 1 | 0xXX：寄存器高字节，分：例如21分则该字节为0x21 The high byte of the register is divided: for example, if the division is 21, the byte is 0x21 |
1 | 0xXX：寄存器低字节，秒：例如52秒则该字节为0x52 The lower byte of the register, in seconds: for example, 52 seconds corresponds to 0x52 | |

Maintenance
1、The cloud density monitor with the 'N' marking should be installed facing north.
2、Keep the glass cover of the cloud cover detector clean. Clean the glass cover with the soft cloth provided.
3、Check the appearance of power lines and data communication lines regularly to avoid short circuit.
