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 is specially treated to reduce dust accumulation and effectively prevent environmental interference, ensuring more accurate solar radiation measurements. The sensor supports standard communication protocols, allowing direct reading of current solar radiation values. It has a compact and sleek design that requires minimal installation space. Ideal 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 - Integrated leveling bubble and adjustment handwheel for easy on-site calibration - Supports standard Modbus-RTU protocol - High-transparency dust cover with special surface treatment to minimize dust adhesion - Color: Silver - Material: Metal - Output type: RS485 Package Contents: 1 x Solar Radiation Sensor Note: The package includes only the items listed above. Due to different product batches, the appearance may vary slightly. Light reflection and display differences may cause slight color variations between the image and the actual item. Measurement error allowance is +/- 1-3cm.
