Sunshine Duration Sensor

NBL-W-SDS Highly Accurate Sunshine Duration Sensor Product Overview

The NBL-W-SDS Sunshine Duration Sensor is a high-end weather observation device designed for continuous monitoring of sunshine duration. The sensor integrates precise measurement technology and durable design concepts to ensure stable and highly accurate data in a variety of climatic conditions. By accurately sensing solar radiation, the sensor starts timing when the radiation voltage exceeds a threshold of 200mv and automatically resets at zero point each day to ensure accurate data recording. The design with no moving parts and low power consumption makes the NBL-W-SDS ideal for long-term field deployments. It is widely used in meteorological research, solar power generation, agricultural planning, building design and environmental monitoring.
