CDG-10B Solar Radiation Sensor Pyranometer

Meta Description

Discover the benefits of using a high-accuracy solar radiation sensor (pyranometer) for photovoltaic system performance monitoring, smart farming, and environmental research. Learn how real-time solar irradiance measurement boosts efficiency and data accuracy.

Introduction: Why Solar Radiation Measurement Matters

Solar radiation is crucial for industries like renewable energy, climate science, and precision agriculture. Accurate solar irradiance monitoring enables better decision-making, energy forecasting, and environmental control. That’s where a high-precision solar radiation sensor—also known as a pyranometer—comes in.

If you manage a solar farm, run a smart greenhouse, or operate a weather station, a good pyranometer is key. It helps you collect real-time and accurate solar radiation data in all conditions.

What Is a Solar Radiation Sensor (Pyranometer)?

A solar radiation sensor is a device designed to measure the power of solar irradiance over a surface. Researchers typically use it to record Global Horizontal Irradiance (GHI)—the total shortwave solar radiation received per square meter.

Contemporary pyranometers employ silicon photodiodes or thermopile sensors. They convert sunlight into electrical signals. Researchers then measure these signals in watts per square meter (W/m²). These devices are critical in photovoltaic energy analyzing, climate monitoring, and smart city environmental systems.

Key Features of a High-Accuracy Pyranometer

• Wide Spectral Response (300–1100 nm): This range captures all solar shortwave radiation important for PV and environmental studies.

• Real-Time Solar Irradiance Monitoring: Delivers fast response times (≤5s), ideal for dynamic cloud cover or solar tracking applications.

• Output Options: Compatible with 0–5V, 4–20mA, and RS485 Modbus protocols. This allows easy integration into PLCs, dataloggers, or SCADA systems.

• IP65 Weatherproof Design: Suitable for outdoor use in solar farms, greenhouses, and harsh environments.

• Easy Installation and Low Maintenance: Includes leveling base and smooth dome for minimal cleaning and reliable long-term performance.
