The solar radiation sensor uses the photoelectric principle to measure solar radiation in the range of 0.3~3μm. It features a high-precision photosensitive element with wide spectrum absorption, high absorption rate, and excellent stability. A dust cover with up to 95% light transmittance is installed over the sensing element. The dust cover undergoes special treatment to reduce dust accumulation and effectively prevent environmental interference, ensuring more accurate solar radiation measurements. The sensor adopts a standard communication protocol, allowing direct reading of the current solar radiation value. It has a compact and sleek design, requiring minimal installation space. Suitable for applications in solar energy utilization, meteorology, agriculture, building material aging, and air pollution monitoring. Key features: - High-precision sensor with high absorption across the full spectrum - Includes leveling bubble and adjustment handwheel for easy on-site calibration - Supports standard Modbus-RTU protocol - High-transparency dust cover with enhanced light sensitivity and anti-dust surface treatment Color: Silver Material: Metal Interface type: RS485 Package Contents: 1 x Solar Radiation Sensor Note: The package includes only the items listed above. Product appearance may vary slightly due to different production batches. Light reflection and display differences may cause slight color variations between the image and the actual item. Measurement error is +/- 1-3cm.
