Description

The industrial-grade total solar radiation sensor monitors solar radiation from 300 to 1100 nanometers. Generates a current signal proportional to incident radiation intensity when exposed to illuminating radiation, with sensitivity directly proportional to the cosine of the angle of incidence. The range is 0 to 2000 W/m². Supports MODBUS-RTU RS485 protocol, connecting to RS485 data logger for tailored monitoring.

Rated IP68, this robust total solar radiation sensor operates from -30°C to 75°C, thriving in harsh outdoor conditions. It ensures precise solar radiation measurements, optimizing agricultural management for improved crop yield and quality. It also aids researchers in better utilizing solar energy by enhancing their understanding of radiation.

Application

• Weather Monitoring: Measures solar, ground, and atmospheric radiation, aiding weather forecasting and research.
• Agricultural Study: Explores agricultural meteorology, crop growth, and ecology.
• Environmental Monitoring: Tracks radiation levels to assess environmental impact.
• Energy Research: Supports solar and other energy studies by analyzing radiation conditions.

Measuring total solar radiation is crucial in multiple fields, providing essential data for weather prediction, climate study, solar energy utilization, agriculture, and environmental research. It directly impacts climate trends, solar panel efficiency, crop growth, and energy project feasibility.

For instance, in agriculture, plants respond uniquely to solar radiation, making accurate measurements invaluable for optimizing irrigation, fertilization, and planting strategies based on photosynthesis and lighting needs.
