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 cover undergoes special treatment to reduce dust accumulation and effectively prevents environmental interference, enabling more accurate solar radiation measurements. The product adopts the standard Modbus-RTU communication protocol, allowing direct reading of the current solar radiation value with ease. Compact and sleek design requires minimal installation space. Suitable for applications in solar energy utilization, meteorology, agriculture, building material aging studies, and air pollution monitoring. High-precision sensor ensures reliable performance across the full spectrum range. Comes with leveling base and adjustment handwheel for convenient on-site setup. Dust cover offers high transparency, good light sensitivity, and special surface treatment to resist dust adhesion.
